public abstract class AbstractIntList
extends AbstractIntCollection
implements IntList

Abstract base class for lists of primitive int elements.

This class implements Collection allowing seamless integration with other APIs.

The get(int) and size() methods must be implemented by subclases. To make the subclass modifiable, the add(int, int), removeIndex(int) and set(int, int) must also be implemented. Subclasses may override other methods to increase efficiency.
