Class ObjToIntMap

java.lang.Object

com.google.gwt.dev.js.rhino.ObjToIntMap

All Implemented Interfaces:

Serializable

public class ObjToIntMap
extends Object
implements Serializable

Map to associate objects to integers. The map does not synchronize any of its operation, so either use it from a single thread or do own synchronization or perform all mutation operations on one thread before passing the map to others
