Method Summary
Modifier and TypeMethodDescriptionvoid
close()
Method called at the end of execution, that is, when the run-time execution endsvoid
endCurrentItem
(Item currentItem) Method that is called when an instruction has finished processing a new current item and is ready to select a new current item or revert to the previous current item.void
enter
(InstructionInfo instruction, XPathContext context) Method that is called when an instruction in the stylesheet gets processed.Get the context item stackvoid
leave
(InstructionInfo instruction) Method that is called after processing an instruction of the stylesheet, that is, after any child instructions have been processed.void
open()
Method called at the start of execution, that is, when the run-time transformation startsvoid
startCurrentItem
(Item currentItem) Method that is called by an instruction that changes the current item in the source document: that is, xsl:for-each, xsl:apply-templates, xsl:for-each-group.

open
public void open()Method called at the start of execution, that is, when the run-time transformation starts- Specified by:
open
in interfaceTraceListener
-
close
public void close()Method called at the end of execution, that is, when the run-time execution ends- Specified by:
close
in interfaceTraceListener
-
enter
Method that is 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
Method that is called after processing an instruction of the stylesheet, that is, after any child instructions have been 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
Method that is called by an instruction that changes the current item in the source document: that is, xsl:for-each, xsl:apply-templates, xsl:for-each-group. The method is called after the enter method for the relevant instruction, and is called once for each item processed.- Specified by:
startCurrentItem
in interfaceTraceListener
- Parameters:
currentItem
- the new current item. Item objects are not mutable; it is safe to retain a reference to the Item for later use.
-
endCurrentItem
Method that is called when an instruction has finished processing a new current item and is ready to select a new current item or revert to the previous current item. The method will be called before the leave() method for the instruction that made this item current.- Specified by:
endCurrentItem
in interfaceTraceListener
- Parameters:
currentItem
- 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.
