Detailed Description

A simple helper class to store arbitrary attributes (identified by Strings) for arbitrary objects (identified by String-Ids). Note that this implementation uses large amounts of memory for storing many attributes for many objects, it is not heavily optimized.

This class is not thread-safe.

More information can be found in the package's Javadoc.
