java.lang.Object net.sf.saxon.event.LocationCopier
public class LocationCopier
A Receiver that can be inserted into an event pipeline to copy location information. The class acts as a LocationProvider, so it supports getSystemId() and getLineNumber() methods; the location returned can vary for each node, and is set by the class generating the events. The class is used when it is necessary to copy a subtree along with its location information; for example, when copying an inline schema within a stylesheet to a separate schema document.
Note: prior to 9.2, the LocationCopier was a ProxyReceiver that passed all events on the pipeline unchanged. It no longer does this, instead it is found as the LocationProvider on a pipeline, but does not itself see the pipeline events.
