      • evaluate

        public boolean evaluate​(ScoreNode[] row,
                                Name[] selectorNames,
                                EvaluationContext context)
                         throws IOException

        Specified by:
        evaluate in interface Constraint
        Parameters:
        row - the current row of score nodes.
        selectorNames - the selector names associated with row.
        context - the evaluation context.
        Returns:
        true if the row satisfies the constraint, false otherwise.
