Interface DList

All Superinterfaces:

Collection, DCollection, Iterable, List, SequencedCollection

All Known Implementing Classes:

RasList

public interface DList
extends DCollection, List

The ODMG List collection. A DList collection is an ordered collection that provides efficient insertion and removal of elements at arbitrary positions in the list, but it also supports indexed access. The beginning index value is 0. When an element is added at a given position in the list, the index of all subsequent elements is increased by 1. Similarly, when an element is removed from the list, the index of all subsequent elements is decreased by 1.

All of the operations defined by the JavaSoft List interface are supported by an ODMG implementation of DList, the exception UnsupportedOperationException is not thrown when a call is made to any of the List methods.
