Method Detail

getOpeningAttributes

protected java.lang.String getOpeningAttributes()

Generate attributes to be included in the opening trace element

Specified by:

getOpeningAttributes in class AbstractTraceListener

startCurrentItem

public void startCurrentItem(Item item)

Description copied from class: AbstractTraceListener

Called when an item becomes the context item

Specified by:

startCurrentItem in interface TraceListener

Overrides:

startCurrentItem in class AbstractTraceListener

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)

Description copied from class: AbstractTraceListener

Called after a node of the source tree got processed

Specified by:

endCurrentItem in interface TraceListener

Overrides:

endCurrentItem in class AbstractTraceListener

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.

enter

public void enter(InstructionInfo info,
                  XPathContext context)

Called when an instruction in the stylesheet gets processed

Specified by:

enter in interface TraceListener

Overrides:

enter in class AbstractTraceListener

Parameters:

info - 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 info)

Description copied from class: AbstractTraceListener

Called after an instruction of the stylesheet got processed

Specified by:

leave in interface TraceListener

Overrides:

leave in class AbstractTraceListener

Parameters:

info - 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.

tag

protected java.lang.String tag(int construct)

Specified by:

tag in class AbstractTraceListener
