Method Detail

propagate

public boolean propagate()

Description copied from class: ConstraintSolver

Propagate the constraint network.

Overrides:

propagate in class RCC2ConstraintSolver

Returns:

A boolean value indicating whether propagation was successful.

getRelation

public static GeometricConstraint.Type getRelation(Polygon p1,
                                                   Polygon p2)

getIntersectionPolygon

public static Vec2[] getIntersectionPolygon(Polygon p1,
                                            Polygon p2)

applyDCcliping

public boolean applyDCcliping(Polygon p1,
                              Polygon p2)

getArea

public static double getArea(Vec2[] vertices)

addConstraintsSub

protected boolean addConstraintsSub(Constraint[] c)

Description copied from class: ConstraintSolver

This method must be implemented by the developer of the specific ConstraintSolver class. It should implement all operations necessary to add multiple constraints, and should return true upon success, false otherwise.

Overrides:

addConstraintsSub in class RCC2ConstraintSolver

Parameters:

c - The constraints to add.

Returns:

true iff the constraints were added to the ConstraintNetwork.

removeConstraintsSub

protected void removeConstraintsSub(Constraint[] c)

Description copied from class: ConstraintSolver

This method must be implemented by the developer of the specific ConstraintSolver class. Should implement all operations necessary to remove a batch of constraints.

Overrides:

removeConstraintsSub in class RCC2ConstraintSolver

Parameters:

c - The constraints to remove.

drawPolygons

public static java.lang.String drawPolygons(java.util.Vector<java.util.Vector<Vec2>> toPlots,
                                            long horizon)

setObstacles

public void setObstacles(Variable[] variables)

getObstacles

public Variable[] getObstacles()
