Class ObjectIndex

java.lang.Object

org.josql.incubator.ObjectIndex

All Implemented Interfaces:

Comparator

public class ObjectIndex
extends Object
implements Comparator

This is an experimental class aimed at producing an index across a collection of homogeneous objects. It should be noted here that it is the "sorting" of the elements in the List of objects that takes nearly all the time here. Use the sort() method yourself to only perform sort once. Everytime you add an object however the sort status of the List of objects will be invalidated and have to be re-sorted before you have retrieve the objects again.
