public class WrapperList
extends java.util.AbstractList<java.lang.Object>

A wrapper for an Object array to expose AbstractList methods. The only difference with the class returned by Arrays.asList is that the toArray method does NOT return a clone of the array, but the array itself. This makes it possible to avoid an array copy when converting an Object[] to an ArrayList for instance: // Create an Object array Object[] anArray = ... // The listNoCopy will directly use the anArray array (until it needs to reallocate a new one) ArrayList
