        Parameters:
        attributes - is a map of attribute key to attribute value

      • cbWfInvoke

        public void cbWfInvoke​(Invoke invoke)

        Specified by:
        cbWfInvoke in interface Callback
        Parameters:
        invoke - the invoke object

      • cbJob

        public void cbJob​(Job job)
        Callback for the job from section 2 jobs. These jobs are completely assembled, but each is passed separately.
        Specified by:
        cbJob in interface Callback
        Parameters:
        job - the Job object storing the job information gotten from parser.

      • cbParents

                      java.util.List parents)
        Callback for child and parent relationships from section 3.
        Specified by:
        cbParents in interface Callback
        Parameters:
        child - is the IDREF of the child element.
        parents - is a list of IDREFs of the included parents.

      • cbDone

        public void cbDone()
        Callback when the parsing of the document is done. It sets the flag that the parsing has been done, that is used to determine whether the ADag object has been fully generated or not.

      • getConstructedObject

        public java.lang.Object getConstructedObject()
        Returns an ADag object corresponding to the abstract plan it has generated. It throws a runtime exception if the method is called before the object has been created fully.
        Specified by:
        getConstructedObject in interface Callback
        Returns:
        ADag object containing the abstract plan referred in the dax.
