Type Parameters:
E - The type of elements in the list.
All Implemented Interfaces:

public class CheckedArrayList<E> extends ArrayList<E> implements CheckedCollection<E>, Cloneable
A checked and synchronized List. Type checks are performed at run-time in addition of compile-time checks. The synchronization lock can be modified at runtime by overriding the getLock() method.

This class is similar to using the wrappers provided in Collections, minus the cost of indirection levels and with the addition of overrideable methods.
