Class mxGraphAbstractHierarchyCell

    • Field Detail

      • maxRank

        public int maxRank
        The maximum rank this cell occupies

      • minRank

        public int minRank
        The minimum rank this cell occupies

      • x

        public double[] x
        The x position of this cell for each layer it occupies

      • y

        public double[] y
        The y position of this cell for each layer it occupies

      • width

        public double width
        The width of this cell

      • height

        public double height
        The height of this cell

      • nextLayerConnectedCells

        protected java.util.List<mxGraphAbstractHierarchyCell>[] nextLayerConnectedCells
        A cached version of the cells this cell connects to on the next layer up

      • previousLayerConnectedCells

        protected java.util.List<mxGraphAbstractHierarchyCell>[] previousLayerConnectedCells
        A cached version of the cells this cell connects to on the next layer down

      • temp

        public int[] temp
        Temporary variable for general use. Generally, try to avoid carrying information between stages. Currently, the longest path layering sets temp to the rank position in fixRanks() and the crossing reduction uses this. This meant temp couldn't be used for hashing the nodes in the model dfs and so hashCode was created
