    • Method Detail

      • removeLevelLate

        public void removeLevelLate​(int level)
        Deprecated.
        Description copied from interface: RemoveLevelLate
        This function is called in case of the backtrack. It is called after all timestamps, variables, mutablevariables have reverted to their values *after* removing the level.
        Specified by:
        removeLevelLate in interface RemoveLevelLate
        Parameters:
        level - the level which is being removed.

      • consistency

        public void consistency​(Store store)
        Deprecated.
        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.

      • pruneRelation

        private void pruneRelation​(Store store,
                           byte rel)
        Deprecated.

      • impose

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

      • queueVariable

        public void queueVariable​(int level,
                          Var var)
        Deprecated.
        Description copied from class: Constraint
        This is a function called to indicate which variable in a scope of constraint has changed. It also indicates a store level at which the change has occurred.
        Overrides:
        queueVariable in class Constraint
        Parameters:
        level - the level of the store at which the change has occurred.
        var - variable which has changed.

      • satisfied

        public boolean satisfied()
        Deprecated.
        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.
