Class LocationCopier

  • All Implemented Interfaces:
    javax.xml.transform.Result, CopyInformee, LocationProvider, Receiver
    public class LocationCopier
extends ProxyReceiver
implements CopyInformee, LocationProvider
    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.
