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.

    • open

      public void open()
      Description copied from class: ProxyReceiver
      Start of event stream
      Specified by:
      open in interface Receiver
      Overrides:
      open in class ProxyReceiver

    • close

      public void close()
      Description copied from class: ProxyReceiver
      End of output. Note that closing this receiver also closes the rest of the pipeline.

      close in interface Receiver
      Overrides:
      close in class ProxyReceiver

    • startDocument

      public void startDocument(int properties)
      Description copied from class: ProxyReceiver
      Start of a document node.
      Specified by:
      startDocument in interface Receiver
      Overrides:
      startDocument in class ProxyReceiver
      Parameters:
      properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOption

    • endDocument

      public void endDocument()
      Description copied from class: ProxyReceiver
      Notify the end of a document node
      Specified by:
      endDocument in interface Receiver
      Overrides:
      endDocument in class ProxyReceiver

    • startElement

      public void startElement(NodeName elemName, SchemaType type, AttributeMap attributes, NamespaceMap namespaces, Location location, int properties)
      Description copied from class: ProxyReceiver
      Notify the start of an element
      Specified by:
      startElement in interface Receiver
      Overrides:
      startElement in class ProxyReceiver
      Parameters:
      elemName - the name of the element.
      type - the type annotation of the element.
      attributes - the attributes of this element
      namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements
      location - an object providing information about the module, line, and column where the node originated
      properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption

    • endElement

      public void endElement()
      Description copied from class: ProxyReceiver
      End of element
      Specified by:
      endElement in interface Receiver
      Overrides:
      endElement in class ProxyReceiver
