Class TimingTraceListener

  • All Implemented Interfaces:
    java.util.EventListener, TraceListener

    public class TimingTraceListener
    extends java.lang.Object
    implements TraceListener
    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.

      • setOutputDestination

        public void setOutputDestination​(java.io.PrintStream stream)
        Set the PrintStream to which the output will be written.
        Specified by:
        setOutputDestination in interface TraceListener
        Parameters:
        stream - the PrintStream to be used for output. By default, the output is written to System.err.
        Throws:
        XPathException
        javax.xml.stream.XMLStreamException
      • open

        public void open​(Controller controller)
        Called at start
        Specified by:
        open in interface TraceListener
        Parameters:
        controller - identifies the transformation controller, and provides the listener with access to context and configuration information
      • close

        public void close()
        Called at end. This method builds the XML out and analyzed html output
        Specified by:
        close in interface TraceListener
      • enter

        public void enter​(InstructionInfo instruction,
                          XPathContext context)
        Called when an instruction in the stylesheet gets processed
        Specified by:
        enter in interface TraceListener
        Parameters:
        instruction - gives information about the instruction being executed, and about the context in which it is executed. This object is mutable, so if information from the InstructionInfo is to be retained, it must be copied.
      • leave

        public void leave​(InstructionInfo instruction)
        Called after an instruction of the stylesheet got processed
        Specified by:
        leave in interface TraceListener
        Parameters:
        instruction - gives the same information that was supplied to the enter method, though it is not necessarily the same object. Note that the line number of the instruction is that of the start tag in the source stylesheet, not the line number of the end tag.
      • startCurrentItem

        public void startCurrentItem​(Item item)
        Called when an item becomes current
        Specified by:
        startCurrentItem in interface TraceListener
        Parameters:
        item - the new current item. Item objects are not mutable; it is safe to retain a reference to the Item for later use.
      • endCurrentItem

        public void endCurrentItem​(Item item)
        Called after a node of the source tree got processed
        Specified by:
        endCurrentItem in interface TraceListener
        Parameters:
        item - the item that was current, whose processing is now complete. This will represent the same underlying item as the corresponding startCurrentItem() call, though it will not necessarily be the same actual object.
      • getStyleSheet

        public PreparedStylesheet getStyleSheet()
                                         throws javax.xml.transform.TransformerConfigurationException
        Prepare Stylesheet to render the analyzed XML data out. This method can be overridden in a subclass to produce the output in a different format.
        Throws:
        javax.xml.transform.TransformerConfigurationException
