public class CatchingReceiver extends ProxyReceiver
This class catches all errors thrown by a Receiver pipeline, and reports them to a specified ErrorReporter; after an error has occurred, all further events are ignored. The class is added to a validation pipeline when validation of a streamed input document is requested, to allow a try/catch expression to catch validation errors.
