All Superinterfaces:

All Known Implementing Classes:

ReferenceCountingList

public interface IReferenceCountingList<COMPONENT>
extends List<COMPONENT>

A List that only allows unique elements and keeps a count of the number of attempts to add the element. This provides a reference count for the elements but preserves the initial adding order of the elements. Calling remove on the element will decrement the reference count, when this is 0 the element is removed from the list.
