Package gnu.trove.decorator Description

GNU Trove: Decorators for java.util.{Map,Set} compatability

The classes in this package serve to wrap the Trove primitive collections so that they can be used in operations that require a java.util.Map or java.util.Set.

This is form of adaptation is extremely inefficient and so should only be undertaken as a last resort or when you don't care about performance (in which case Trove is probably not appropriate anyway).

The general pattern here is that you "wrap" a Trove collection with the appropriate decorator object to obtain a java.util.Map or Set. The implementations do not retain references to the Objects they accept/return (all calls are delegated to the underlying trove collection), so you should not rely on object identity within those collections.

You may extend the decorator classes to use canonical values if your dataset permits. For some applications, this will help reduce the cost of (un)wrapping primitive values. Note, however, that such datasets are probably small/restricted enough that you should again ask yourself whether Trove is appropriate in the first place. Caveat programmer.
