Class ContentHandlerProxy.ContentHandlerProxyTraceListener

java.lang.Object

net.sf.saxon.event.ContentHandlerProxy.ContentHandlerProxyTraceListener

All Implemented Interfaces:

java.util.EventListener, TraceListener

Enclosing class:

ContentHandlerProxy

public static class ContentHandlerProxy.ContentHandlerProxyTraceListener
extends java.lang.Object
implements TraceListener

Create a TraceListener that will collect information about the current location in the source document. This is used to provide information to the receiving application for diagnostic purposes.

Method Summary

Modifier and Type	Method and Description
void	close() Method called at the end of execution, that is, when the run-time execution ends
void	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.
java.util.Stack	getContextItemStack() Get the context item stack
void	open(Controller controller) Method called at the start of execution, that is, when the run-time transformation starts
void	setOutputDestination(Logger stream) Method called to supply the destination for output
void	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.

Constructor Detail

ContentHandlerProxyTraceListener

public ContentHandlerProxyTraceListener()

Method Detail

setOutputDestination

public void setOutputDestination(Logger stream)

Description copied from interface: TraceListener

Method called to supply the destination for output

Specified by:

setOutputDestination in interface TraceListener

Parameters:

stream - a Logger to which any output produced by the TraceListener should be written

getContextItemStack

public java.util.Stack getContextItemStack()

Get the context item stack

Returns:

the context item stack

open

public void open(Controller controller)

Method called at the start of execution, that is, when the run-time transformation starts

Specified by:

open in interface TraceListener

Parameters:

controller - identifies the transformation controller, and provides the listener with access to context and configuration information

close

public void close()

Method called at the end of execution, that is, when the run-time execution ends

Specified by:

close in interface TraceListener

startCurrentItem

public void 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. The method is called after the enter method for the relevant instruction, and is called once for each item processed.

Specified by:

startCurrentItem in interface TraceListener

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

public void 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. The method will be called before the leave() method for the instruction that made this item current.

Specified by:

endCurrentItem in interface TraceListener

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.
