Package net.sf.saxon.trace
Class TimingTraceListener
java.lang.Object
net.sf.saxon.trace.TimingTraceListener
- All Implemented Interfaces:
EventListener
,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.

Method Details

setOutputDestination
Set the PrintStream to which the output will be written.- Specified by:
setOutputDestination
in interfaceTraceListener
- Parameters:
stream
- the PrintStream to be used for output. By default, the output is written to System.err.- Throws:
XPathException
XMLStreamException
-
open
Called at start- Specified by:
open
in interfaceTraceListener
- 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 interfaceTraceListener
-
enter
Called when an instruction in the stylesheet gets processed- Specified by:
enter
in interfaceTraceListener
- 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
Called after an instruction of the stylesheet got processed- Specified by:
leave
in interfaceTraceListener
- 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
Called when an item becomes current- Specified by:
startCurrentItem
in interfaceTraceListener
- 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
Called after a node of the source tree got processed- Specified by:
endCurrentItem
in interfaceTraceListener
- 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
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.
