  • All Implemented Interfaces:
    java.io.Serializable

    public class ObjToIntMap
    extends java.lang.Object
    implements java.io.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
