/**
* Wrapper class to make a TObjectIntHashMap conform to the java.util.Map API.
* This class simply decorates an underlying TObjectIntHashMap and translates the Object-based
* APIs into their Trove primitive analogs.
*
*
* Note that wrapping and unwrapping primitive values is extremely inefficient. If
* possible, users of this class should override the appropriate methods in this class
* and use a table of canonical values.
