java.lang.Object net.sf.saxon.event.ContentHandlerProxy.ContentHandlerProxyTraceListener
public static class ContentHandlerProxy.ContentHandlerProxyTraceListener
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 | |
---|---|
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. |
void |
enter(InstructionInfo instruction,
XPathContext context)
Method that is called when an instruction in the stylesheet gets processed. |
Stack |
getContextItemStack()
Get the context item stack |
void |
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(Controller controller)
Method called at the start of execution, that is, when the run-time transformation starts |
void |
setOutputDestination(PrintStream 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. |

public void setOutputDestination(PrintStream stream)
TraceListener
setOutputDestination
in interface TraceListener
stream
- a PrintStream to which any output produced by the TraceListener should be writtenpublic Stack getContextItemStack()
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(InstructionInfo instruction, 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.public void leave(InstructionInfo instruction)
leave
in interface TraceListener
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.public void startCurrentItem(Item currentItem)
startCurrentItem
in interface TraceListener
currentItem
- 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 currentItem)
endCurrentItem
in interface TraceListener
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.
