      After parsing the document, this method must be called to get the Object. This method can only be called once, because after calling the internal variables are resetted to reuse the object.
      Specified by:
      getObject in class AbstractXMLHandler
    • isHandlerFor

      public boolean isHandlerFor(String uri, String localName, String qName, Attributes attributes)
      Queries the handler for possible handling of the given (SAX-)parameters
      Specified by:
      isHandlerFor in class AbstractXMLHandler
    • startElement

      public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException
      Specified by:
      startElement in interface ContentHandler
    • getName

      public String getName()
      Each io component must have a name that is used in IOFactory.newIO(String). The name must be unique thus it is usefull to use a short description or to the class name ( this.getClass().getName()).
      Specified by:
      getName in interface IO
      Returns the name of the io component.
    • isHandlerFor

      public boolean isHandlerFor(Class value)
      Checks if the io component is capable to perform the operation for objects of this class.

      A typical implementation looks like:

       public boolean isHandlerFor(Class value) {
              if (DataObject.class.isAssignableFrom(value))
                      return true;
              return false;
      Specified by:
      isHandlerFor in interface IO
      value - The class that has to be checked.
      Results true if the class can oeprate with the given class.
    • copy

      public IO copy()

      Specified by:
      copy in interface IO
    • endElement

      public void endElement(String uri, String localName, String qName) throws SAXException
      Specified by:
      endElement in interface ContentHandler
    • subHandlerFinishedWithObject

      public void subHandlerFinishedWithObject(Object subHandlerObject)
