public class ContentHandlerProxyLocator extends Object implements Locator
When the ContentHandler is used to receive the results of a query or stylesheet, the information supplied by the standard methods such as ContentHandlerProxyLocator and ContentHandlerProxyLocator 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.
