Class Values

    • Field Detail

      • idNumber

        static final java.util.concurrent.atomic.AtomicInteger idNumber
      • list

        private final IntVar[] list
        It specifies a list of variables which are counted.
      • count

        private final IntVar count
        It specifies the idNumber of different values among variables on a given list.
      • minFDV

        java.util.Comparator<IntVar> minFDV
    • Constructor Detail

      • Values

        public Values​(IntVar[] list,
                      IntVar count)
        It constructs Values constraint.
        Parameters:
        list - list of variables for which different values are being counted.
        count - specifies the number of different values in the list.
      • Values

        public Values​(java.util.List<? extends IntVar> list,
                      IntVar count)
        It constructs Values constraint.
        Parameters:
        list - list of variables for which different values are being counted.
        count - specifies the number of different values in the list.
    • Method Detail

      • consistency

        public void consistency​(Store store)
        Description copied from class: Constraint
        It is a (most probably incomplete) consistency function which removes the values from variables domains. Only values which do not have any support in a solution space are removed.
        Specified by:
        consistency in class Constraint
        Parameters:
        store - constraint store within which the constraint consistency is being checked.
      • toString

        public java.lang.String toString()
        Description copied from class: Constraint
        It produces a string representation of a constraint state.
        Overrides:
        toString in class Constraint
      • satisfied

        public boolean satisfied()
        Description copied from interface: SatisfiedPresent
        It checks if the constraint is satisfied. It can return false even if constraint is satisfied but not all variables in its scope are grounded. It needs to return true if all variables in its scope are grounded and constraint is satisfied.

        Implementations of this interface for constraints that are not PrimitiveConstraint may require constraint imposition and consistency check as a requirement to work correctly.

        Specified by:
        satisfied in interface SatisfiedPresent
        Returns:
        true if constraint is possible to verify that it is satisfied.
