  org.apache.tapestry.engine.DefaultTemplateSource

All Implemented Interfaces:

ITemplateSource, IRenderDescription

public class DefaultTemplateSource
extends Object
implements ITemplateSource, IRenderDescription

Default implementation of ITemplateSource. Templates, once parsed, stay in memory until explicitly cleared.

An instance of this class acts as a singleton shared by all sessions, so it must be threadsafe.
