Description
| Interface Summary | |
|---|---|
| InstructionInfo | Information about an instruction in the stylesheet or a construct in a Query, made available at run-time to a TraceListener |
| Class Summary | |
|---|---|
| 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 XSLT |
| ContextStackFrame.BuiltInTemplateRule | Subclass of ContextStackFrame representing a built-in template rule in XSLT |
| ContextStackFrame.CallingApplication | Subclass of ContextStackFrame representing the outermost stack frame, for the calling application |
| ContextStackFrame.CallTemplate | Subclass of ContextStackFrame representing an xsl:call-template instruction in XSLT |
| ContextStackFrame.FunctionCall | Subclass of ContextStackFrame representing a call to a user-defined function either in XSLT or XQuery |
| ContextStackFrame.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. |
| ExpressionPresenter | This class handles the display of an abstract expression tree in an XML format with some slight resemblence to XQueryX |
| Location | This class holds constants identifying different kinds of location in a source stylesheet or query. |
| TimingCodeInjector | 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 evaluation |
| TimingTraceListener | 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 evaluated |
| TraceEventMulticaster | A class which implements efficient and thread-safe multi-cast event dispatching for the TraceListener evants. |
| XQueryTraceListener | A Simple trace listener for XQuery that writes messages (by default) to System.err |
| XSLTTraceCodeInjector | 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 evaluated |
| XSLTTraceListener | A Simple trace listener for XSLT that writes messages (by default) to System.err |
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.
