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.

Interface Summary Interface Description ExpressionPresenter.Options InstructionInfo Information about an instruction in the stylesheet or a construct in a Query, made available at run-time to a TraceListener.Traceable A construct whose execution can be notified to a TraceListener.TraceableComponent A construct whose execution can be notified to a TraceListener. -
Class Summary Class Description AbstractTraceListener This is the standard trace listener used when the -T option is specified on the command line.ContextStackFrame An entry on the context stack.ContextStackFrame.ApplyTemplates Subclass of ContextStackFrame representing an xsl:apply-templates call in XSLTContextStackFrame.BuiltInTemplateRule Subclass of ContextStackFrame representing a built-in template rule in XSLTContextStackFrame.CallingApplication Subclass of ContextStackFrame representing the outermost stack frame, for the calling applicationContextStackFrame.CallTemplate Subclass of ContextStackFrame representing an xsl:call-template instruction in XSLTContextStackFrame.FunctionCall Subclass of ContextStackFrame representing a call to a user-defined function either in XSLT or XQueryContextStackFrame.VariableEvaluation Subclass of ContextStackFrame representing the evaluation of a variable (typically a global variable)ContextStackIterator This class provides a representation of the current runtime call stack, as represented by the stack of XPathContext objects.CountingFilter A filter that can be inserted into a Receiver pipeline to count the events that pass through.ExpressionPresenter This class handles the display of an abstract expression tree in an XML format with some slight resemblance to XQueryXExpressionPresenter.ExportOptions Instrumentation Internal class used for instrumentation purposes.ModeTraceListener A trace listener for XSLT that only handles invocation of template rules; enabled using saxon:trace="yes" on the xsl:mode declarationTimingCodeInjector A 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 evaluationTimingTraceListener A 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.TraceCodeInjector 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 evaluatedTraceEventMulticaster A class which implements efficient and thread-safe multi-cast event dispatching for the TraceListener evants.TracingFilter A filter that can be inserted into a Receiver pipeline to trace the events that pass through.XQueryTraceCodeInjector A code injector designed to support the -T tracing option in XQueryXQueryTraceListener A Simple trace listener for XQuery that writes messages (by default) to System.errXSLTTraceCodeInjector 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 evaluatedXSLTTraceListener A Simple trace listener for XSLT that writes messages (by default) to System.err
