Method Detail
-
open
public void open()
Called at start- Specified by:
open
in interfaceTraceListener
-
close
public void close()
Called at end- Specified by:
close
in interfaceTraceListener
-
enter
public void enter(InstructionInfo instruction, XPathContext context)
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
public void leave(InstructionInfo instruction)
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
public void startCurrentItem(Item item)
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
public void endCurrentItem(Item item)
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.
