        public void genAttrPresentTest​(ContextMethodBuilder mb)
        Description copied from interface: IComponent
        Generate code to test for attribute present. This generates code that tests if a child is present as determined by attributes of the containing start tag. It leaves the result of the test (zero if missing, nonzero if present) on the stack. This call is only valid if this component has one or more attributes for the containing element.
        Specified by:

        public void genAttributeUnmarshal​(ContextMethodBuilder mb)
        Description copied from interface: IComponent
        Generate attribute unmarshalling code. This is called within the code generation for the unmarshaller of the class associated with the containing element. It needs to generate the necessary code for handling the unmarshalling operation, leaving the unmarshalled object reference on the stack.
        Specified by:
        genAttributeUnmarshal in interface IComponent
        Parameters:
        mb - method builder

      • genAttributeMarshal

        public void genAttributeMarshal​(ContextMethodBuilder mb)
        Description copied from interface: IComponent
        Generate attribute marshalling code. This is called within the code generation for the marshaller of the class associated with the containing element. It needs to generate the necessary code for handling the marshalling operation, consuming the marshalled object reference from the stack.
        Specified by:
        genAttributeMarshal in interface IComponent
        Parameters:
        mb - method builder

        Description copied from interface: IComponent
        Check if component defines one or more elements or text values as children of the containing element. This method is only valid after the call to ILinkable.setLinkages().
        Specified by:
        hasContent in interface IComponent
        Returns:

        Description copied from interface: IComponent
        Generate element or text unmarshalling code. This is called within the code generation for the unmarshaller of the class associated with the containing element.

        genLoadId in interface IComponent
        Parameters:
        mb - method builder

                 throws org.jibx.runtime.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.
        Specified by:
        setLinkages in interface ILinkable
        Throws:
        org.jibx.runtime.JiBXException - if error in configuration
