Package org.ametys.runtime.cocoon

Class ThreadSafeTraxProcessor

java.lang.Object

org.apache.avalon.framework.logger.AbstractLogEnabled

org.ametys.runtime.cocoon.ThreadSafeTraxProcessor

All Implemented Interfaces:

URIResolver, Disposable, Initializable, Component, LogEnabled, Parameterizable, Serviceable, XSLTProcessor

public class ThreadSafeTraxProcessor
extends AbstractLogEnabled
implements XSLTProcessor, Serviceable, Initializable, Disposable, Parameterizable, URIResolver

Adaptation of Excalibur's XSLTProcessor implementation to allow for better error reporting. This implementation is also threadsafe.
It also handles a Templates cache, for performance purpose.
