Constructor Detail

OrBool

public OrBool(IntVar[] a,
              IntVar result)

It constructs and constraint on variables.

Parameters:

a - parameters

result - result variable.

OrBool

public OrBool(List<IntVar> a,
              IntVar result)

It constructs and constraint on variables.

Parameters:

a - parameters

result - result variable.

OrBool

public OrBool(IntVar a,
              IntVar b,
              IntVar result)

It constructs and constraint on variables.

Parameters:

a - a parameter

b - b parameter

result - result variable.

Method Detail

imposeDecomposition

public void imposeDecomposition(Store store)

Description copied from class: DecomposedConstraint

It imposes the constraint in a given store.

Specified by:

imposeDecomposition in class DecomposedConstraint<PrimitiveConstraint>

Parameters:

store - the constraint store to which the constraint is imposed to.

decompose

public List<PrimitiveConstraint> decompose(Store store)

Description copied from class: DecomposedConstraint

It returns an array list of constraint which are used to decompose this constraint. It actually creates a decomposition (possibly also creating variables), but it does not impose the constraint.

Specified by:

decompose in class DecomposedConstraint<PrimitiveConstraint>

Parameters:

store - the constraint store in which context the decomposition takes place.

Returns:

an array list of constraints used to decompose this constraint.

toString

public String toString()

Overrides:

toString in class Object
