public void setOutputDestination(Logger 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(Traceable instruction, java.util.Map<java.lang.String,java.lang.Object> properties, 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.properties
- extra information about the instruction to be included in the tracecontext
- the XPath evaluation contextpublic void leave(Traceable instruction)
leave
in interface TraceListener
instruction
- the instruction or other construct that has now finished executionpublic 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.Copyright (c) 2004-2022 Saxonica Limited. All rights reserved.
