Runtime Engine for RELAXNGCC execution. This class has the following functionalities:
  1. Managing a stack of NGCCHandler objects and switching between them appropriately.
  2. Keep track of all Attributes.
  3. manage mapping between namespace URIs and prefixes.
  4. TODO: provide support for interleaving.

      public NGCCRuntime()

  • Method Details

    • setRootHandler

      public void setRootHandler(NGCCHandler rootHandler)
      Sets the root handler, which will be used to parse the root element.

      This method can be called right after the object is created or the reset method is called. You can't replace the root handler while parsing is in progress.

      Usually a generated class that corresponds to the <start> pattern will be used as the root handler, but any NGCCHandler can be a root handler.

      Parameters:
      rootHandler - new root handler
      Throws:
      IllegalStateException - If this method is called but it doesn't satisfy the pre-condition stated above.

    • reset

      public void reset()
      Cleans up all the data structure so that the object can be reused later. Normally, applications do not need to call this method directly, as the runtime resets itself after the endDocument method.

    • setDocumentLocator

      public void setDocumentLocator(Locator _loc)
      Specified by:
      setDocumentLocator in interface ContentHandler

    • getLocator

      public Locator getLocator()
      Gets the source location of the current event.

      One can call this method from RelaxNGCC handlers to access the line number information. Note that to

      Returns:
      the source location of the current event

    • getCurrentAttributes

      public Attributes getCurrentAttributes()
      Attributes that belong to the current element.

      It's generally not recommended for applications to use this method. RelaxNGCC internally removes processed attributes, so this doesn't correctly reflect all the attributes an element carries.

      Returns:
      Attributes that belong to the current element

    • replace

      public int replace(NGCCEventReceiver o, NGCCEventReceiver n)
      Description copied from interface: NGCCEventSource
      Replaces an old handler with a new handler, and returns ID of the EventReceiver thread.
      Specified by:
      replace in interface NGCCEventSource
      Parameters:
      o - old handler
      n - new handler
      Returns:
      Thread ID of the receiver that can handle this event, or -1 if none.

    • processList

      public void processList(String str) throws SAXException
      Throws:
      SAXException

    • startElement

      public void startElement(String uri, String localname, String qname, Attributes atts) throws SAXException
      Specified by:
      startElement in interface ContentHandler
      Throws:
      SAXException

    • onEnterElementConsumed

      public void onEnterElementConsumed(String uri, String localName, String qname, Attributes atts) throws SAXException
      Called by the generated handler code when an enter element event is consumed.

      Pushes a new attribute set.

      Note that attributes are NOT pushed at the startElement method, because the processing of the enterElement event can trigger other attribute events and etc.

      This method will be called from one of handlers when it truly consumes the enterElement event.

      Parameters:
      uri - Parameter passed to the element event.
      localName - Parameter passed to the element event.
      qname - Parameter passed to the element event.
      atts - Parameter passed to the element event.
      Throws:
      SAXException - for errors

    • onLeaveElementConsumed

      public void onLeaveElementConsumed(String uri, String localName, String qname) throws SAXException
      Parameters:
      uri - Parameter passed to the element event.
      localName - Parameter passed to the element event.
      qname - Parameter passed to the element event.
      Throws:
      SAXException - for errors

    • endElement

      public void endElement(String uri, String localname, String qname) throws SAXException
      Specified by:
      endElement in interface ContentHandler
