Examples of RhinoEngine

org.jaggeryjs.scriptengine.engine.RhinoEngine
The RhinoEngine class acts as a global engine for executing JavaScript codes using Mozilla Rhino. Each engine instance associates a scope and a caching manager.
During the class initialization time, it creates a static global scope, which will be cloned upon request. This also has a constructor which accepts class object itself as a parameter. So, it allows you to keep customised versions of RhinoEngine instances.
It also has several util methods to register hostobjects, methods, properties with the engine's scope.

This class provides methods to create JavaScript objects from JavaScript files. @author Hannes Wallnoefer
