/**
* A <em>lookup object</em> is a factory for creating method handles,
* when the creation requires access checking.
* Method handles do not perform
* access checks when they are called, but rather when they are created.
* Therefore, method handle access
* restrictions must be enforced when a method handle is created.
* The caller class against which those restrictions are enforced
* is known as the {@linkplain #lookupClass lookup class}.
* <p>
* A lookup class which needs to create method handles will call
* {@link MethodHandles#lookup MethodHandles.lookup} to create a factory for itself.
* When the {@code Lookup} factory object is created, the identity of the lookup class is
* determined, and securely stored in the {@code Lookup} object.
* The lookup class (or its delegates) may then use factory methods
* on the {@code Lookup} object to create method handles for access-checked members.
* This includes all methods, constructors, and fields which are allowed to the lookup class,
* even private ones.
*
* <h1><a name="lookups"></a>Lookup Factory Methods</h1>
* The factory methods on a {@code Lookup} object correspond to all major
* use cases for methods, constructors, and fields.
* Each method handle created by a factory method is the functional
* equivalent of a particular <em>bytecode behavior</em>.
* (Bytecode behaviors are described in section 5.4.3.5 of the Java Virtual Machine Specification.)
* Here is a summary of the correspondence between these factory methods and
* the behavior of the resulting method handles:

*
* Here, the type {@code C} is the class or interface being searched for a member,
* documented as a parameter named {@code refc} in the lookup methods.
* The method type {@code MT} is composed from the return type {@code T}
* and the sequence of argument types {@code A*}.
* The constructor also has a sequence of argument types {@code A*} and
* is deemed to return the newly-created object of type {@code C}.
* Both {@code MT} and the field type {@code FT} are documented as a parameter named {@code type}.
* The formal parameter {@code this} stands for the self-reference of type {@code C};
* if it is present, it is always the leading argument to the method handle invocation.
* (In the case of some {@code protected} members, {@code this} may be
* restricted in type to the lookup class; see below.)
* The name {@code arg} stands for all the other method handle arguments.
* In the code examples for the Core Reflection API, the name {@code thisOrNull}
* stands for a null reference if the accessed method or field is static,
* and {@code this} otherwise.
* The names {@code aMethod}, {@code aField}, and {@code aConstructor} stand
* for reflective objects corresponding to the given members.
* <p>
* The bytecode behavior for a {@code findClass} operation is a load of a constant class,
* as if by {@code ldc CONSTANT_Class}.
* The behavior is represented, not as a method handle, but directly as a {@code Class} constant.
* <p>
* In cases where the given member is of variable arity (i.e., a method or constructor)
* the returned method handle will also be of {@linkplain MethodHandle#asVarargsCollector variable arity}.
* In all other cases, the returned method handle will be of fixed arity.
* <p style="font-size:smaller;">
* <em>Discussion:</em>
* The equivalence between looked-up method handles and underlying
* class members and bytecode behaviors
* can break down in a few ways:
* <ul style="font-size:smaller;">
* <li>If {@code C} is not symbolically accessible from the lookup class's loader,
* the lookup can still succeed, even when there is no equivalent
* Java expression or bytecoded constant.
* <li>Likewise, if {@code T} or {@code MT}
* is not symbolically accessible from the lookup class's loader,
* the lookup can still succeed.
* For example, lookups for {@code MethodHandle.invokeExact} and
* {@code MethodHandle.invoke} will always succeed, regardless of requested type.
* <li>If there is a security manager installed, it can forbid the lookup
* on various grounds (<a href="MethodHandles.Lookup.html#secmgr">see below</a>).
* By contrast, the {@code ldc} instruction on a {@code CONSTANT_MethodHandle}
* constant is not subject to security manager checks.
* <li>If the looked-up method has a
* <a href="MethodHandle.html#maxarity">very large arity</a>,
* the method handle creation may fail, due to the method handle
* type having too many parameters.
* </ul>
*
* <h1><a name="access"></a>Access checking</h1>
* Access checks are applied in the factory methods of {@code Lookup},
* when a method handle is created.
* This is a key difference from the Core Reflection API, since
* {@link java.lang.reflect.Method#invoke java.lang.reflect.Method.invoke}
* performs access checking against every caller, on every call.
* <p>
* All access checks start from a {@code Lookup} object, which
* compares its recorded lookup class against all requests to
* create method handles.
* A single {@code Lookup} object can be used to create any number
* of access-checked method handles, all checked against a single
* lookup class.
* <p>
* A {@code Lookup} object can be shared with other trusted code,
* such as a metaobject protocol.
* A shared {@code Lookup} object delegates the capability
* to create method handles on private members of the lookup class.
* Even if privileged code uses the {@code Lookup} object,
* the access checking is confined to the privileges of the
* original lookup class.
* <p>
* A lookup can fail, because
* the containing class is not accessible to the lookup class, or
* because the desired class member is missing, or because the
* desired class member is not accessible to the lookup class, or
* because the lookup object is not trusted enough to access the member.
* In any of these cases, a {@code ReflectiveOperationException} will be
* thrown from the attempted lookup. The exact class will be one of
* the following:
* <ul>
* <li>NoSuchMethodException — if a method is requested but does not exist
* <li>NoSuchFieldException — if a field is requested but does not exist
* <li>IllegalAccessException — if the member exists but an access check fails
* </ul>
* <p>
* In general, the conditions under which a method handle may be
* looked up for a method {@code M} are no more restrictive than the conditions
* under which the lookup class could have compiled, verified, and resolved a call to {@code M}.
* Where the JVM would raise exceptions like {@code NoSuchMethodError},
* a method handle lookup will generally raise a corresponding
* checked exception, such as {@code NoSuchMethodException}.
* And the effect of invoking the method handle resulting from the lookup
* is <a href="MethodHandles.Lookup.html#equiv">exactly equivalent</a>
* to executing the compiled, verified, and resolved call to {@code M}.
* The same point is true of fields and constructors.
* <p style="font-size:smaller;">
* <em>Discussion:</em>
* Access checks only apply to named and reflected methods,
* constructors, and fields.
* Other method handle creation methods, such as
* {@link MethodHandle#asType MethodHandle.asType},
* do not require any access checks, and are used
* independently of any {@code Lookup} object.
* <p>
* If the desired member is {@code protected}, the usual JVM rules apply,
* including the requirement that the lookup class must be either be in the
* same package as the desired member, or must inherit that member.
* (See the Java Virtual Machine Specification, sections 4.9.2, 5.4.3.5, and 6.4.)
* In addition, if the desired member is a non-static field or method
* in a different package, the resulting method handle may only be applied
* to objects of the lookup class or one of its subclasses.
* This requirement is enforced by narrowing the type of the leading
* {@code this} parameter from {@code C}
* (which will necessarily be a superclass of the lookup class)
* to the lookup class itself.
* <p>
* The JVM imposes a similar requirement on {@code invokespecial} instruction,
* that the receiver argument must match both the resolved method <em>and</em>
* the current class. Again, this requirement is enforced by narrowing the
* type of the leading parameter to the resulting method handle.
* (See the Java Virtual Machine Specification, section 4.10.1.9.)
* <p>
* The JVM represents constructors and static initializer blocks as internal methods
* with special names ({@code "<init>"} and {@code "<clinit>"}).
* The internal syntax of invocation instructions allows them to refer to such internal
* methods as if they were normal methods, but the JVM bytecode verifier rejects them.
* A lookup of such an internal method will produce a {@code NoSuchMethodException}.
* <p>
* In some cases, access between nested classes is obtained by the Java compiler by creating
* an wrapper method to access a private method of another class
* in the same top-level declaration.
* For example, a nested class {@code C.D}
* can access private members within other related classes such as
* {@code C}, {@code C.D.E}, or {@code C.B},
* but the Java compiler may need to generate wrapper methods in
* those related classes. In such cases, a {@code Lookup} object on
* {@code C.E} would be unable to those private members.
* A workaround for this limitation is the {@link Lookup#in Lookup.in} method,
* which can transform a lookup on {@code C.E} into one on any of those other
* classes, without special elevation of privilege.
* <p>
* The accesses permitted to a given lookup object may be limited,
* according to its set of {@link #lookupModes lookupModes},
* to a subset of members normally accessible to the lookup class.
* For example, the {@link MethodHandles#publicLookup publicLookup}
* method produces a lookup object which is only allowed to access
* public members in public classes of exported packages.
* The caller sensitive method {@link MethodHandles#lookup lookup}
* produces a lookup object with full capabilities relative to
* its caller class, to emulate all supported bytecode behaviors.
* Also, the {@link Lookup#in Lookup.in} method may produce a lookup object
* with fewer access modes than the original lookup object.
*
* <p style="font-size:smaller;">
* <a name="privacc"></a>
* <em>Discussion of private access:</em>
* We say that a lookup has <em>private access</em>
* if its {@linkplain #lookupModes lookup modes}
* include the possibility of accessing {@code private} members.
* As documented in the relevant methods elsewhere,
* only lookups with private access possess the following capabilities:
* <ul style="font-size:smaller;">
* <li>access private fields, methods, and constructors of the lookup class
* <li>create method handles which invoke <a href="MethodHandles.Lookup.html#callsens">caller sensitive</a> methods,
* such as {@code Class.forName}
* <li>create method handles which {@link Lookup#findSpecial emulate invokespecial} instructions
* <li>avoid <a href="MethodHandles.Lookup.html#secmgr">package access checks</a>
* for classes accessible to the lookup class
* <li>create {@link Lookup#in delegated lookup objects} which have private access to other classes
* within the same package member
* </ul>
* <p style="font-size:smaller;">
* Each of these permissions is a consequence of the fact that a lookup object
* with private access can be securely traced back to an originating class,
* whose <a href="MethodHandles.Lookup.html#equiv">bytecode behaviors</a> and Java language access permissions
* can be reliably determined and emulated by method handles.
*
* <h1><a name="secmgr"></a>Security manager interactions</h1>
* Although bytecode instructions can only refer to classes in
* a related class loader, this API can search for methods in any
* class, as long as a reference to its {@code Class} object is
* available. Such cross-loader references are also possible with the
* Core Reflection API, and are impossible to bytecode instructions
* such as {@code invokestatic} or {@code getfield}.
* There is a {@linkplain java.lang.SecurityManager security manager API}
* to allow applications to check such cross-loader references.
* These checks apply to both the {@code MethodHandles.Lookup} API
* and the Core Reflection API
* (as found on {@link java.lang.Class Class}).
* <p>
* If a security manager is present, member and class lookups are subject to
* additional checks.
* From one to three calls are made to the security manager.
* Any of these calls can refuse access by throwing a
* {@link java.lang.SecurityException SecurityException}.
* Define {@code smgr} as the security manager,
* {@code lookc} as the lookup class of the current lookup object,
* {@code refc} as the containing class in which the member
* is being sought, and {@code defc} as the class in which the
* member is actually defined.
* (If a class or other type is being accessed,
* the {@code refc} and {@code defc} values are the class itself.)
* The value {@code lookc} is defined as <em>not present</em>
* if the current lookup object does not have
* <a href="MethodHandles.Lookup.html#privacc">private access</a>.
* The calls are made according to the following rules:
* <ul>
* <li><b>Step 1:</b>
* If {@code lookc} is not present, or if its class loader is not
* the same as or an ancestor of the class loader of {@code refc},
* then {@link SecurityManager#checkPackageAccess
* smgr.checkPackageAccess(refcPkg)} is called,
* where {@code refcPkg} is the package of {@code refc}.
* <li><b>Step 2a:</b>
* If the retrieved member is not public and
* {@code lookc} is not present, then
* {@link SecurityManager#checkPermission smgr.checkPermission}
* with {@code RuntimePermission("accessDeclaredMembers")} is called.
* <li><b>Step 2b:</b>
* If the retrieved class has a {@code null} class loader,
* and {@code lookc} is not present, then
* {@link SecurityManager#checkPermission smgr.checkPermission}
* with {@code RuntimePermission("getClassLoader")} is called.
* <li><b>Step 3:</b>
* If the retrieved member is not public,
* and if {@code lookc} is not present,
* and if {@code defc} and {@code refc} are different,
* then {@link SecurityManager#checkPackageAccess
* smgr.checkPackageAccess(defcPkg)} is called,
* where {@code defcPkg} is the package of {@code defc}.
* </ul>
* Security checks are performed after other access checks have passed.
* Therefore, the above rules presuppose a member or class that is public,
* or else that is being accessed from a lookup class that has
* rights to access the member or class.
*
* <h1><a name="callsens"></a>Caller sensitive methods</h1>
* A small number of Java methods have a special property called caller sensitivity.
* A <em>caller-sensitive</em> method can behave differently depending on the
* identity of its immediate caller.
* <p>
* If a method handle for a caller-sensitive method is requested,
* the general rules for <a href="MethodHandles.Lookup.html#equiv">bytecode behaviors</a> apply,
* but they take account of the lookup class in a special way.
* The resulting method handle behaves as if it were called
* from an instruction contained in the lookup class,
* so that the caller-sensitive method detects the lookup class.
* (By contrast, the invoker of the method handle is disregarded.)
* Thus, in the case of caller-sensitive methods,
* different lookup classes may give rise to
* differently behaving method handles.
* <p>
* In cases where the lookup object is
* {@link MethodHandles#publicLookup() publicLookup()},
* or some other lookup object without
* <a href="MethodHandles.Lookup.html#privacc">private access</a>,
* the lookup class is disregarded.
* In such cases, no caller-sensitive method handle can be created,
* access is forbidden, and the lookup fails with an
* {@code IllegalAccessException}.
* <p style="font-size:smaller;">
* <em>Discussion:</em>
* For example, the caller-sensitive method
* {@link java.lang.Class#forName(String) Class.forName(x)}
* can return varying classes or throw varying exceptions,
* depending on the class loader of the class that calls it.
* A public lookup of {@code Class.forName} will fail, because
* there is no reasonable way to determine its bytecode behavior.
* <p style="font-size:smaller;">
* If an application caches method handles for broad sharing,
* it should use {@code publicLookup()} to create them.
* If there is a lookup of {@code Class.forName}, it will fail,
* and the application must take appropriate action in that case.
* It may be that a later lookup, perhaps during the invocation of a
* bootstrap method, can incorporate the specific identity
* of the caller, making the method accessible.
* <p style="font-size:smaller;">
* The function {@code MethodHandles.lookup} is caller sensitive
* so that there can be a secure foundation for lookups.
* Nearly all other methods in the JSR 292 API rely on lookup
* objects to check access requests.

* guaranteed with respect to the largest power of two that divides the GCD
* of {@code A} and the size (in bytes) of {@code T}.
* If access is aligned then following access modes are supported and are

* <li>read write access modes for all {@code T};
* <li>atomic update access modes for {@code int}, {@code long},
* {@code float} or {@code double}.

* (Future major platform releases of the JDK may support additional

* {@code index}, {@code T} and it's corresponding boxed type,
* {@code T_BOX}, as follows:

/**
* Constructs a method handle representing a loop with several loop variables that are updated and checked upon each
* iteration. Upon termination of the loop due to one of the predicates, a corresponding finalizer is run and
* delivers the loop's result, which is the return value of the resulting handle.
* <p>
* Intuitively, every loop is formed by one or more "clauses", each specifying a local iteration value and/or a loop
* exit. Each iteration of the loop executes each clause in order. A clause can optionally update its iteration
* variable; it can also optionally perform a test and conditional loop exit. In order to express this logic in
* terms of method handles, each clause will determine four actions:<ul>
* <li>Before the loop executes, the initialization of an iteration variable or loop invariant local.
* <li>When a clause executes, an update step for the iteration variable.
* <li>When a clause executes, a predicate execution to test for loop exit.
* <li>If a clause causes a loop exit, a finalizer execution to compute the loop's return value.
* </ul>
* <p>
* Some of these clause parts may be omitted according to certain rules, and useful default behavior is provided in
* this case. See below for a detailed description.
* <p>
* Each clause function, with the exception of clause initializers, is able to observe the entire loop state,
* because it will be passed <em>all</em> current iteration variable values, as well as all incoming loop
* parameters. Most clause functions will not need all of this information, but they will be formally connected as
* if by {@link #dropArguments}.
* <p>
* Given a set of clauses, there is a number of checks and adjustments performed to connect all the parts of the
* loop. They are spelled out in detail in the steps below. In these steps, every occurrence of the word "must"
* corresponds to a place where {@link IllegalArgumentException} may be thrown if the required constraint is not met
* by the inputs to the loop combinator. The term "effectively identical", applied to parameter type lists, means
* that they must be identical, or else one list must be a proper prefix of the other.
* <p>
* <em>Step 0: Determine clause structure.</em><ol type="a">
* <li>The clause array (of type {@code MethodHandle[][]} must be non-{@code null} and contain at least one element.
* <li>The clause array may not contain {@code null}s or sub-arrays longer than four elements.
* <li>Clauses shorter than four elements are treated as if they were padded by {@code null} elements to length
* four. Padding takes place by appending elements to the array.
* <li>Clauses with all {@code null}s are disregarded.
* <li>Each clause is treated as a four-tuple of functions, called "init", "step", "pred", and "fini".
* </ol>
* <p>
* <em>Step 1A: Determine iteration variables.</em><ol type="a">
* <li>Examine init and step function return types, pairwise, to determine each clause's iteration variable type.
* <li>If both functions are omitted, use {@code void}; else if one is omitted, use the other's return type; else
* use the common return type (they must be identical).
* <li>Form the list of return types (in clause order), omitting all occurrences of {@code void}.
* <li>This list of types is called the "common prefix".
* </ol>
* <p>
* <em>Step 1B: Determine loop parameters.</em><ul>
* <li><b>If at least one init function is given,</b><ol type="a">
* <li>Examine init function parameter lists.
* <li>Omitted init functions are deemed to have {@code null} parameter lists.
* <li>All init function parameter lists must be effectively identical.
* <li>The longest parameter list (which is necessarily unique) is called the "common suffix".
* </ol>
* <li><b>If no init function is given,</b><ol type="a">
* <li>Examine the suffixes of the step, pred, and fini parameter lists, after removing the "common prefix".
* <li>The longest of these suffixes is taken as the "common suffix".
* </ol></ul>
* <p>
* <em>Step 1C: Determine loop return type.</em><ol type="a">
* <li>Examine fini function return types, disregarding omitted fini functions.
* <li>If there are no fini functions, use {@code void} as the loop return type.
* <li>Otherwise, use the common return type of the fini functions; they must all be identical.
* </ol>
* <p>
* <em>Step 1D: Check other types.</em><ol type="a">
* <li>There must be at least one non-omitted pred function.
* <li>Every non-omitted pred function must have a {@code boolean} return type.
* </ol>
* <p>
* <em>Step 2: Determine parameter lists.</em><ol type="a">
* <li>The parameter list for the resulting loop handle will be the "common suffix".
* <li>The parameter list for init functions will be adjusted to the "common suffix". (Note that their parameter
* lists are already effectively identical to the common suffix.)
* <li>The parameter list for non-init (step, pred, and fini) functions will be adjusted to the common prefix
* followed by the common suffix, called the "common parameter sequence".
* <li>Every non-init, non-omitted function parameter list must be effectively identical to the common parameter
* sequence.
* </ol>
* <p>
* <em>Step 3: Fill in omitted functions.</em><ol type="a">
* <li>If an init function is omitted, use a {@linkplain #constant constant function} of the appropriate
* {@code null}/zero/{@code false}/{@code void} type. (For this purpose, a constant {@code void} is simply a
* function which does nothing and returns {@code void}; it can be obtained from another constant function by
* {@linkplain MethodHandle#asType type conversion}.)
* <li>If a step function is omitted, use an {@linkplain #identity identity function} of the clause's iteration
* variable type; insert dropped argument parameters before the identity function parameter for the non-{@code void}
* iteration variables of preceding clauses. (This will turn the loop variable into a local loop invariant.)
* <li>If a pred function is omitted, the corresponding fini function must also be omitted.
* <li>If a pred function is omitted, use a constant {@code true} function. (This will keep the loop going, as far
* as this clause is concerned.)
* <li>If a fini function is omitted, use a constant {@code null}/zero/{@code false}/{@code void} function of the
* loop return type.
* </ol>
* <p>
* <em>Step 4: Fill in missing parameter types.</em><ol type="a">
* <li>At this point, every init function parameter list is effectively identical to the common suffix, but some
* lists may be shorter. For every init function with a short parameter list, pad out the end of the list by
* {@linkplain #dropArguments dropping arguments}.
* <li>At this point, every non-init function parameter list is effectively identical to the common parameter
* sequence, but some lists may be shorter. For every non-init function with a short parameter list, pad out the end
* of the list by {@linkplain #dropArguments dropping arguments}.
* </ol>
* <p>
* <em>Final observations.</em><ol type="a">
* <li>After these steps, all clauses have been adjusted by supplying omitted functions and arguments.
* <li>All init functions have a common parameter type list, which the final loop handle will also have.
* <li>All fini functions have a common return type, which the final loop handle will also have.
* <li>All non-init functions have a common parameter type list, which is the common parameter sequence, of
* (non-{@code void}) iteration variables followed by loop parameters.
* <li>Each pair of init and step functions agrees in their return types.
* <li>Each non-init function will be able to observe the current values of all iteration variables, by means of the
* common prefix.
* </ol>
* <p>
* <em>Loop execution.</em><ol type="a">
* <li>When the loop is called, the loop input values are saved in locals, to be passed (as the common suffix) to
* every clause function. These locals are loop invariant.
* <li>Each init function is executed in clause order (passing the common suffix) and the non-{@code void} values
* are saved (as the common prefix) into locals. These locals are loop varying (unless their steps are identity
* functions, as noted above).
* <li>All function executions (except init functions) will be passed the common parameter sequence, consisting of
* the non-{@code void} iteration values (in clause order) and then the loop inputs (in argument order).
* <li>The step and pred functions are then executed, in clause order (step before pred), until a pred function
* returns {@code false}.
* <li>The non-{@code void} result from a step function call is used to update the corresponding loop variable. The
* updated value is immediately visible to all subsequent function calls.
* <li>If a pred function returns {@code false}, the corresponding fini function is called, and the resulting value
* is returned from the loop as a whole.
* </ol>
* <p>
* Here is pseudocode for the resulting loop handle. In the code, {@code V}/{@code v} represent the types / values

* value returned from the {@code cleanup} handle's execution will be the result of the execution of the
* {@code try-finally} handle.
* <p>
* The {@code cleanup} handle will be passed one or two additional leading arguments.
* The first is the exception thrown during the

* The second argument is not present if the {@code target} handle has a {@code void} return type.
* (Note that, except for argument type conversions, combinators represent {@code void} values in parameter lists
* by omitting the corresponding paradoxical arguments, not by inserting {@code null} or zero values.)
* <p>

* that the {@code cleanup} handle may omit trailing arguments. Also, the {@code cleanup} handle must have one or

* This parameter is not present if the {@code target} returns {@code void}.
* </ul>
* <p>
* The pseudocode for the resulting adapter looks as follows. In the code, {@code V} represents the result type of
* the {@code try/finally} construct; {@code A}/{@code a}, the types and values of arguments to the resulting
* handle consumed by the cleanup; and {@code B}/{@code b}, those of arguments to the resulting handle discarded by
* the cleanup.
* <blockquote><pre>{@code

* <p>
* Note that the saved arguments ({@code a...} in the pseudocode) cannot
* be modified by execution of the target, and so are passed unchanged
* from the caller to the cleanup, if it is invoked.
* <p>
* The target and cleanup must return the same type, even if the cleanup
* always throws.
* To create such a throwing cleanup, compose the cleanup logic
* with {@link #throwException throwException},
* in order to create a method handle of the correct return type.
