Examples of bsh.NameSpace

bsh.NameSpace
A namespace in which methods, variables, and imports (class names) live. This is package public because it is used in the implementation of some bsh commands. However for normal use you should be using methods on bsh.Interpreter to interact with your scripts.
A bsh.This object is a thin layer over a NameSpace that associates it with an Interpreter instance. Together they comprise a Bsh scripted object context.
Note: I'd really like to use collections here, but we have to keep this compatible with JDK1.1
