Interface TraceListener2

All Superinterfaces:

EventListener, TraceListener

All Known Implementing Classes:

AbstractTraceListener, ModeTraceListener, XQueryTraceListener, XSLTTraceListener

public interface TraceListener2
extends TraceListener

This interface defines methods that are called by Saxon during the execution of a stylesheet, if tracing is switched on. Tracing can be switched on by nominating an implementation of this class using the TRACE_LISTENER feature of the TransformerFactory, or using the addTraceListener() method of the Controller, which is Saxon's implementation of the JAXP javax.xml.transform.Transformer interface.

Since:

9.7. The TraceListener2 interface extends the TraceListener interface, which is retained for compatibility.
