public void setOutputDestination(PrintStream stream)
setOutputDestination
in interface TraceListener
stream
- the PrintStream to be used for output. By default, the output is written
to System.err.

public void open(Controller controller)
open
in interface TraceListener
controller
- identifies the transformation controller, and provides the listener with
access to context and configuration informationpublic void close()
close
in interface TraceListener
public void enter(InstructionInfo instruction, XPathContext context)
enter
in interface TraceListener
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.public void leave(InstructionInfo instruction)
leave
in interface TraceListener
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.public void startCurrentItem(Item item)
startCurrentItem
in interface TraceListener
item
- the new current item. Item objects are not mutable; it is safe to retain
a reference to the Item for later use.public void endCurrentItem(Item item)
endCurrentItem
in interface TraceListener
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.public PreparedStylesheet getStyleSheet() throws TransformerConfigurationException
TransformerConfigurationException
