java.lang.Object java.util.AbstractMap<java.lang.Double,java.lang.Byte> gnu.trove.decorator.TDoubleByteMapDecorator
public class TDoubleByteMapDecorator
Wrapper class to make a TDoubleByteMap conform to the java.util.Map API. This class simply decorates an underlying TDoubleByteMap 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. Created: Mon Sep 23 22:07:40 PDT 2002
