    • genParseIdRef

      private void genParseIdRef(ContextMethodBuilder mb) throws JiBXException

      JiBXException - if error in configuration

    • genIfPresentTest

      Parameters:
      mb - unmarshal method builder
      Throws:
      JiBXException - if configuration error

    • setLinkages

      public void setLinkages() throws JiBXException
      Description copied from interface: ILinkable
      Establish and validate linkages between binding components. This is called after the basic binding structures have been set up. All linkages between components must be resolved by this method, in order to prevent problems due to the order of definitions between components. This implies that each component must in turn call the same method for each child component. None of the other method calls defined by this interface are valid until after this call.
