gnu.trove.decorator.TLongDoubleHashMapDecorator
Wrapper class to make a TLongDoubleHashMap conform to the java.util.Map API. This class simply decorates an underlying TLongDoubleHashMap 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.
