public final class ObjectModelHelper

extends java.lang.Object

A set of constants and methods to access the content of the object model.

The object model is a Map used to pass information about the calling environment to the sitemap and its components (matchers, actions, transformers, etc).

This class provides accessors only for the objects in the object model that are common to every environment and which can thus be used safely. Some environments provide additional objects, but they are not described here and accessing them should be done in due cause since this ties the application to that particular environment.
