public abstract class AbstractLongCollection
extends AbstractPrimitiveCollectable<java.lang.Long>
implements LongCollection

Abstract base class for collections of primitive long elements.

This class implements Collection allowing seamless integration with other APIs.

The iterator and size must be implemented by subclases. To make the subclass modifiable, the add(long) and iterator remove() methods must also be implemented. Subclasses may override other methods to increase efficiency.
