      • getIndex

        public int getIndex()
        Get the index that this object has in the underlying model. Attention: this is a very advanced function. Use it only if you know exactly what you are doing.

        Used in these examples:

        • GlobalObjectiveParametrics
        • GlobalRHSParametrics
        Specified by:
        getIndex in interface  Index
        Returns:
        The index of this object in the underlying model.
        Since:
        43.00

      • updateIndex

        public void updateIndex​(int delta)
        Specified by:
        updateIndex in interface  Index
        Parameters:
        delta - The value to add to the index.
        Since:
        43.00

      • getIndexForProb

        public int getIndexForProb​(XpressProblem xprob)
        Get the index stored in this object but raise an exception if the problem that created this object is not prob.
        Specified by:
        getIndexForProb in interface  Index
        Parameters:
        xprob - The problem for which the index is queried. If this object does not belong to prob then an execption is raised.
        Returns:
        The low-level index for this object in prob.
        Since:
        43.00

      • getProblem

        public XpressProblem getProblem()
        Get the problem to which this element belongs.
        Specified by:
        getProblem in interface  Index
        Returns:
        The problem to which this element belongs. This will be null if the element was deleted.
