      • genTestPresent

        public void genTestPresent​(ContextMethodBuilder mb)
                            throws JiBXException
        Generate presence test code for this mapping. The generated code finds the unmarshaller and calls the test method, leaving the result on the stack.
        Parameters:
        mb - method builder
        Throws:
        JiBXException - if error in generating code
      • genUnmarshal

                          throws JiBXException
        Generate unmarshalling code for this mapping. The generated code finds and calls the unmarshaller with the object to be unmarshaller (which needs to be loaded on the stack by the code prior to this call, but may be null). The unmarshalled object (or null in the case of a missing optional item) is left on the stack after this call. The calling method generally needs to cast this object reference to the appropriate type before using it.
        Parameters:
        mb - method builder
        Throws:
        JiBXException - if error in generating code
      • genMarshal

        public void genMarshal​(ContextMethodBuilder mb)
                        throws JiBXException
        Generate marshalling code for this mapping. The generated code finds and calls the marshaller, passing the object to be marshalled (which should have been loaded to the stack by the prior generated code)..
        Parameters:
        mb - method builder
        Throws:
        JiBXException - if error in configuration
      • getTargetClass

        Returns:
        marshaller class information
        Throws:
        JiBXException - if error in transformation

                                  throws JiBXException
        Get unmarshaller class used for mapping. If a name has been supplied the actual unmarshaller class is created by extending the base class the first time this method is called.
