public abstract class AbstractDoubleList
extends AbstractDoubleCollection
implements DoubleList

Abstract base class for lists of primitive double 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, double), removeIndex(int) and set(int, double) must also be implemented. Subclasses may override other methods to increase efficiency.
