      • 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.
      • swap

        private void swap​(int i,
                          int j)
      • include

        public void include​(Store store)
        Description copied from interface: StoreAware
        It provide store for constraints that are not imposed but called from other constraints.
        Specified by:
        include in interface StoreAware
        Overrides:
        include in class PrimitiveConstraint
        Parameters:
        store - the constraint store in which context the constraint is executed.
      • impose

        public void impose​(Store store)
        Description copied from class: Constraint
        It imposes the constraint in a given store.
        Overrides:
        impose in class PrimitiveConstraint
        Parameters:
        store - the constraint store to which the constraint is imposed to.
      • 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.
      • 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.
      • 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
