      • 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.

        Specified by:
        getIndex in interface  Index
        Returns:
        The index of this object in the underlying model.

        Specified by:
        getIndexForProb in interface  Index
        Parameters:
        prob - The problem for which the index is queried. If this object does not belong to prob then an execption is raised.
