ImmutableArrayList

java.lang.Object
- java.util.AbstractCollection
  - java.util.AbstractList
    - java.util.ArrayList

public class ImmutableArrayList extends ArrayList

Subclasses ArrayList but throws an UnsupportedOperationException from any method that would change the internal data members. Any iterators that are returned do the same. All other methods are delegated to the ArrayList that is passed to the constructor, so creating an instance of this class does not result in making a copy of the internal element array of the source array list.
