Class IdentityIntMap

java.lang.Object
  extended by com.caucho.hessian.util.IdentityIntMap

public class IdentityIntMap
extends java.lang.Object

The IntMap provides a simple hashmap from keys to integers. The API is an abbreviation of the HashMap collection API.

The convenience of IntMap is avoiding all the silly wrapping of integers.
