    • labeledValue

      int labeledValue
      The labeled value associated with the edge when it is a contingent link or a wait constraint. Its value is Constants.INT_NULL when this edge is ordinary.

    • caseLabel

      STNUEdge.CaseLabel caseLabel
      The upper/lower case label.

      The first component is the node label; the second specifies the nature: true for upper-case, false for lower-case.

    • resetLabeledValue

      public int resetLabeledValue()
      Removes the labeled value and makes the edges an ordinary constraint if it was contingent.

    • setLabeledValue

      public int setLabeledValue(ALabelAlphabet.ALetter nodeALetter, int w, boolean upperCase)
      Description copied from interface: STNUEdge
      Sets the labeled weight to w of a Edge.ConstraintType.contingent edge. If nodeLabel == null or w = Constants.INT_NULL, the possible labeled value is removed.

      If a wait must be set, use STNUEdge.updateWait(int, ALetter).

      Specified by:
      setLabeledValue in interface STNUEdge
      Parameters:
      nodeALetter - the name of the contingent node as ALetter.
      w - the new weight value
      upperCase - true if the edge is an upper-case edge, false it is a lower-case edge. In the case of lower-case edge, w must be positive.
      Returns:
      the old weight associated with the edge. If the weight was not set, it returns Constants.INT_NULL.

    • updateValue

      public boolean updateValue(int v)
      If the edge is not a wait, it sets the ordinary value if v is smaller than the current one. If the edge is a wait, it sets the ordinary value if v is negative. Moreover, if v is smaller (i.e., stronger) than the wait value, the wait is removed.
      Specified by:
      updateValue in interface STNEdge
      Overrides:
      updateValue in class STNEdgeInt
      Parameters:
      v - the new weight value
