AbstractContext

class InternalContextBase

extends java.lang.Object

implements InternalHousekeepingContext, InternalEventContext, java.io.Serializable

class to encapsulate the 'stuff' for internal operation of velocity. We use the context as a thread-safe storage : we take advantage of the fact that it's a visitor of sorts to all nodes (that matter) of the AST during init() and render(). Currently, it carries the template name for namespace support, as well as node-local context data introspection caching. Note that this is not a public class. It is for package access only to keep application code from accessing the internals, as AbstractContext is derived from this.
