Package net.sf.saxon.trace
package net.sf.saxon.trace
This package provides an interface to Saxon tracing and debugging capabilities.
The package was originally created by Edwin Glaser.
The package includes three tracing modules that can be optionally selected:
XSLTTraceListener
, XQueryTraceListener
, and
TimedTraceListener
. These all receive notification of the same events,
but select and format the events in different ways to meet different requirements.
Other events are notified through the TraceListener
interface that
are ignored by tracing applications, but may be of interest to debuggers.

ClassDescriptionThis is the standard trace listener used when the -T option is specified on the command line.An entry on the context stack.Subclass of ContextStackFrame representing an xsl:apply-templates call in XSLTSubclass of ContextStackFrame representing a built-in template rule in XSLTSubclass of ContextStackFrame representing the outermost stack frame, for the calling applicationSubclass of ContextStackFrame representing an xsl:call-template instruction in XSLTSubclass of ContextStackFrame representing an xsl:for-each instruction in XSLTSubclass of ContextStackFrame representing a call to a user-defined function either in XSLT or XQuerySubclass of ContextStackFrame representing the evaluation of a variable (typically a global variable)This class provides a representation of the current runtime call stack, as represented by the stack of XPathContext objects.This class handles the display of an abstract expression tree in an XML format with some slight resemblence to XQueryXInformation about an instruction in the stylesheet, made available at run-time to a TraceListenerThis class holds constants identifying different kinds of location in a source stylesheet or query.A Simple trace listener that writes messages to System.errA class which implements efficient and thread-safe multi-cast event dispatching for the TraceListener evants.This interface defines methods that are called by Saxon during the execution of a stylesheet, if tracing is switched on.A Simple trace listener for XQuery that writes messages (by default) to System.errA Simple trace listener for XSLT that writes messages (by default) to System.err
