1,616,867 | 1,616,868 | How can I create a copy of my data type I created in Java? | <p>If I have a class:</p>
<pre><code>public class MyType

public MyType(List<Integer> myData, boolean myFlag)
{
this.data = myData;
this.myFlag = someFlag;
}
}
</code></pre>
<p>Now, if I create an instance of MyType, how do I do a deep copy of it? I don't want the new object to point to the old reference, but an entirely new instance.</p>
<p>Is this a case when I should implement the Cloneable interface, or is that a used for shallow copies? </p>
<p>I can't just do:</p>
<pre><code>MyType instance1 = new MyType(someData, false);
MyType instance2 = new MyType(instance1.getData(), instance1.getFlag());
</code></pre>
<p>I'm concerned about new instances of MyType pointing to the same reference for its "data" variable. So I need to copy it entirely.</p>
<p>So, if I have an existing object:</p>
<pre><code>MyType someVar = new MyType(someList, false);
// Now, I want a copy of someVar, not another variable pointing to the same reference.
</code></pre>
<p>Can someone point me in the right direction?</p>

Is it possible to invoke the static methods of the actual class using the 'name of the class' in the string array.</p>
<pre><code>public class SortCompare {
// There are classes called 'Insertion', 'Selection' and 'Shell' which have a
// method called 'sort'
private static String[] algorithm = { "Insertion", "Selection", "Shell"};
public static double timeTheRun(String alg, Comparable[] a) {
for (int i = 0; i < algorithm.length; i++)
if (alg.equalsIgnoreCase(algorithm[i])) {
Stopwatch timer = new Stopwatch();
// I want to invoke one of Insertion.sort(), Selection.sort()
// or Shell.sort() depending on the value of 'alg' here
break;
}
return timer.elapsedTime();
}
</code></pre>
<p>I could forget about the array of strings and simple use a if-else block to invoke them.</p>
<pre><code> if (alg.equals("Insertion"))
Insertion.sort(a);
else if (alg.equals("Selection"))
Selection.sort(a);
else if (alg.equals("Shell"))
Shell.sort(a);
</code></pre>
<p>But I will keep implementing other sorts and variations of them in future and every time I will have to make changes in multiple places(The above if-else loop, the help message of my program). If the former approach is possible then I'll just have to insert an extra string to the array every time.</p>

int a_;
};
struct DERIVED: public BASE{

<p>then I fill up a std::vector (or boost::ptr_vector)</p>
<pre><code>std::vector<BASE* > vec;
vec.push_back( new BASE(2));
vec.push_back( new DERIVED);
</code></pre>
<p>If I call my function foo, no pb the virtual stuff works well,
but if I create two free functions :</p>
<pre><code>void foo(BASE* a, DERIVED* b){
std::cout << " mix base/derived " << std::endl;
}
void foo(BASE* a, BASE* b){
std::cout << " full base " << std::endl;
}

<p>if I do </p>

<p>I will get the message </p>
<pre><code>full base
</code></pre>
<p>Well it is logical because I have vector of BASE*, but does it exist anyway
to get the good call to my free function ? I need the inheritance so I can not really separate the 2 classes because I must fill up this container</p>
<p>Moreover at the end my vector will be fill up randomly, so I can not know by advance how cast properly.</p>

I can't even figure out what php function needs to be used, but I'm thinking probably a regex. I attempted to use in_array and it didn't work. I don't know enough about regexes to even set up a test. Here's the problem... Say my array is:</p>
<pre><code>$sizeopts = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '.5',
' Wide', ' Narrow', 'XS', 'Small', 'Medium', 'Large', 'XL');
</code></pre>
<p>The textbox name is "size", and I want to only allow combinations of the above to be submitted. Example valid input: "10.5 Wide" or "3XL". Invalid input: "1X" or "2Wide" (missing the space in front of Wide). I have several different size arrays I need to validate. I'm not just using drop-downs because there are two many different possible combinations. Thanks for any help you can offer!</p>
