] | Adds the deprecated key to the global deprecation map when no custom
message is provided.
It does not override any existing entries in the deprecation map.
This is to be used only by the developers in order to add deprecation of
keys, and attempts to call this method after loading resources once,
would lead to <tt>UnsupportedOperationException</tt>
If a key is deprecated in favor of multiple keys, they are all treated as
aliases of each other, and setting any one of them resets all the others
to the new value.
If you have multiple deprecation entries to add, it is more efficient to
use #addDeprecations(DeprecationDelta[] deltas) instead.
@param key Key that is to be deprecated
@param newKeys list of keys that take up the values of deprecated key
@deprecated use {@link #addDeprecation(String key, String newKey)} instead | [

(1). JDK relies on the operating system clock for time.
Each operating system has its own method of handling date changes such as
leap seconds(e.g. OS will slow down the clock to accommodate for this).
(2). DST(Daylight Saving Time) is a legal issue, governments changed it
over time. Some days are NOT exactly 24 hours long, it could be 23/25 hours
long on the first or last day of daylight saving time.
JDK can handle DST correctly.

... | Returns the unary operator's return type.
<p>This method can extract a type in 4 different ways:
<p>1. By using the generics of the base class like MyFunction<X, Y, Z, IN, OUT>.
This is what outputTypeArgumentIndex (in this example "4") is good for.
<p>2. By using input type inference SubMyFunction<T, String, String, String, T>.
This is what inputTypeArgumentIndex (in this example "0") and inType is good for.
<p>3. By using the static method that a compiler generates for Java lambdas.
This is what lambdaOutputTypeArgumentIndices is good for. Given that MyFunction has
the following single abstract method:
<pre>
<code>
void apply(IN value, Collector<OUT> value)
</code>
</pre>
<p> Lambda type indices allow the extraction of a type from lambdas. To extract the
output type <b>OUT</b> from the function one should pass {@code new int[] {1, 0}}.
"1" for selecting the parameter and 0 for the first generic in this type.
Use {@code TypeExtractor.NO_INDEX} for selecting the return type of the lambda for
extraction or if the class cannot be a lambda because it is not a single abstract
method interface.
<p>4. By using interfaces such as {@link TypeInfoFactory} or {@link ResultTypeQueryable}.
<p>See also comments in the header of this class.
