    • Field Detail

      • idNumber

        static java.util.concurrent.atomic.AtomicInteger idNumber
      • x

        public IntVar x
        It specifies variable x whose domain must lie within a specified domain.
      • dom

        public IntDomain dom
        It specifies domain d which restricts the possible value of the specified variable.
      • DomComplement

        private IntDomain DomComplement
        It specifies all the values which can not be taken by a variable.
    • Constructor Detail

      • In

        public In​(IntVar x,
                  IntDomain dom)
        It constructs an In constraint to restrict the domain of the variable.
        Parameters:
        x - variable x for which the restriction is applied.
        dom - the domain to which the variables domain is restricted.
    • 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.
      • notConsistency

        public void notConsistency​(Store store)
        Description copied from class: PrimitiveConstraint
        It makes pruning in such a way that constraint is notConsistent. It removes values which always belong to a solution.
        Specified by:
        notConsistency in class PrimitiveConstraint
        Parameters:
        store - the constraint store in which context the notConsistency technique is evaluated.
      • notSatisfied

        public boolean notSatisfied()
        Description copied from class: PrimitiveConstraint
        It checks if constraint would be always not satisfied.
        Specified by:
        notSatisfied in class PrimitiveConstraint
        Returns:
        true if constraint must be notSatisfied, false otherwise.
      • 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.

        Returns:
        true if constraint is possible to verify that it is satisfied.
      • 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
      • getGuideConstraint

        public Constraint getGuideConstraint()
        Description copied from class: Constraint
        It specifies a constraint which if imposed by search will enhance propagation of this constraint.
        Overrides:
        getGuideConstraint in class Constraint
        Returns:
        Constraint enhancing propagation of this constraint.
      • getGuideValue

        public int getGuideValue()
        Description copied from class: Constraint
        This function provides a value which if assigned to a variable returned by getGuideVariable() will enhance propagation of this constraint.
        Overrides:
        getGuideValue in class Constraint
        Returns:
        Value which is a base of enhancing constraint.
      • getGuideVariable

        public Var getGuideVariable()
        Description copied from class: Constraint
        This function provides a variable which assigned a value returned by will enhance propagation of this constraint.
        Overrides:
        getGuideVariable in class Constraint
        Returns:
        Variable which is a base of enhancing constraint.
      • supplyGuideFeedback

        public void supplyGuideFeedback​(boolean feedback)
        Description copied from class: Constraint
        This function allows to provide a guide feedback. If constraint does not propose sufficiently good enhancing constraints it will be informed so it has a chance to reexamine its efforts.
        Overrides:
        supplyGuideFeedback in class Constraint
        Parameters:
        feedback - true if the guide was useful, false otherwise.
