Package net.sf.saxon.trace
package net.sf.saxon.trace
This package provides an interface to Saxon tracing and debugging capabilities.
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 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.A filter that can be inserted into a Receiver pipeline to count the events that pass through.This class handles the display of an abstract expression tree in an XML format with some slight resemblance to XQueryXInternal class used for instrumentation purposes.A trace listener for XSLT that only handles invocation of template rules; enabled using saxon:trace="yes" on the xsl:mode declarationA code injector that wraps the body of a template or function in a TraceExpression, which causes the TimingTraceListener to be notified at the start and end of the function/template evaluationA trace listener that records timing information for templates and functions, outputting this information as an HTML report to a specified destination when the transformation completes.A construct whose execution can be notified to a TraceListener.A construct whose execution can be notified to a TraceListener.A code injector that wraps every expression (other than a literal) in a TraceExpression, which causes a TraceListener to be notified when the expression is evaluatedA class which implements efficient and thread-safe multi-cast event dispatching for the TraceListener evants.A filter that can be inserted into a Receiver pipeline to trace the events that pass through.A code injector designed to support the -T tracing option in XQueryA Simple trace listener for XQuery that writes messages (by default) to System.errA code injector that wraps every expression (other than a literal) in a TraceExpression, which causes a TraceListener to be notified when the expression is evaluatedA Simple trace listener for XSLT that writes messages (by default) to System.err
