net.sf.saxon.event.ContentHandlerProxyLocator
- Locator
public class ContentHandlerProxyLocator
extends java.lang.Object
implements Locator
Implementation of Locator, used to supply location information to the ContentHandler.
When the ContentHandler is used to receive the results of a query or stylesheet,
the information supplied by the standard methods such as
getSystemId()
and
getLineNumber()
relates to the position of the expression/instruction in the stylesheet
or query that caused the relevant nodes to be output.
If the ContentHandler is used in other contexts, for example as the destination of an
IdentityTransformer, the information reflects the position in the source document.
If the output property
saxon:supply-source-locator
was set to the
value "yes" (which in turn requires that tracing was enabled at compile time), the Locator will
also contain information about the current location in the source document (specifically, the position
of the context node). This will not always be 100% accurate, since there is some buffering of events
in the output pipeline: it reflects the context node at the time the event reaches the ContentHandler,
which may not be the same as the context node at the time the relevant instruction was executed;
however, it still provides some information that may be useful for diagnostics.
ContentHandlerProxyLocator
public ContentHandlerProxyLocator(ContentHandlerProxy parent)
Create the Locator for a ContentHandlerProxy
parent
- the ContentHandlerProxy
getColumnNumber
public int getColumnNumber()
Get the column number
getContextItemStack
public Stack getContextItemStack()
Get the current item stack. This is a Stack, whose members are objects of class
Item
. The top item in the stack is the context node or atomic value; items
further down the stack represent previous context node or atomic value
- the stack of context items
getLineNumber
public int getLineNumber()
Get the line number
- the line number giving the location of the most recent event notified
getPublicId
public String getPublicId()
Get the Public ID
getSystemId
public String getSystemId()
Get the System ID
- the system ID giving the location in the query or stylesheet of the most recent event notified
