Method Detail

getType

getRCCConstraint

public static RCCConstraint.Type getRCCConstraint(AllenIntervalConstraint.Type x,
                                                  AllenIntervalConstraint.Type y)

createInternalConstraints

protected Constraint[] createInternalConstraints(Variable from,
                                                 Variable to)

Description copied from class: MultiBinaryConstraint

This method must be defined to create the internal constraints underlying this MultiBinaryConstraint.

Specified by:

createInternalConstraints in class MultiBinaryConstraint

Parameters:

from - The source Variable of the MultiConstraint.

to - The destination Variable of the MultiConstraint.

Returns:

An array of lower-level constraints which "implement" this MultiBinaryConstraint.

isEquivalent

public boolean isEquivalent(Constraint c)

Description copied from class: Constraint

Method for assessing the "equivalence" between two constraints. This is not used for lookups nor comparisons (hence, it is not the equals method).

Specified by:

isEquivalent in class Constraint

Parameters:

c - The Constraint to compare against.

Returns:

true iff the two constraints are considered to be equivalent.

clone

public java.lang.Object clone()

Description copied from class: MultiConstraint

A MultiConstraint must be cloneable. This is used by the MultiConstraintSolver class to instantiate proper constraints to delegate its underlying ConstraintSolvers.

Specified by:

clone in class MultiConstraint

toString

public java.lang.String toString()

Description copied from class: Constraint

Every Constraint should implement a toString method (used by the ConstraintNetwork rendering methods).

Overrides:

toString in class MultiBinaryConstraint

Returns:

the String representation of this Constraint.

getEdgeLabel

public java.lang.String getEdgeLabel()

Description copied from class: Constraint

Every Constraint should implement this method - its value is what is drawn by the ConstraintNetwork rendering methods.

Specified by:

getEdgeLabel in class Constraint

Returns:

a String representation of the constraint to be used for ConstraintNetwork rendering.
