Class GeometricShapeVariable

java.lang.Object

org.metacsp.framework.Variable

org.metacsp.multi.spatial.DE9IM.GeometricShapeVariable

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Variable>

public class GeometricShapeVariable
extends Variable

Represents a variable that can be reasoned upon by the DE9IMRelationSolver. A GeometricShapeVariable should be provided a domain representing one of the following geometric entities: point (provided by class PointDomain), line string (provided by class LineStringDomain), and polygon (provided by class PolygonalDomain).

Method Detail

getShapeType

public java.lang.Class<?> getShapeType()

Returns the class used to represent the domain of this variable.

Returns:

The class used to represent the domain of this variable.

compareTo

public int compareTo(Variable o)

getDomain

public Domain getDomain()

Description copied from class: Variable

Get the domain of this Variable. Must be implemented by the ConstraintSolver developer, since getting the domain of a variable may be a non-trivial operation.

Specified by:

getDomain in class Variable

Returns:

The domain of the variable.

setDomain

public void setDomain(Domain d)

Description copied from class: Variable

Set the domain of this variable. Must be implemented by the ConstraintSolver developer, since setting the domain of a variable may be a non-trivial operation.

Specified by:

setDomain in class Variable

Parameters:

d - The domain of the variable.

toString

public java.lang.String toString()

Description copied from class: Variable

Get a String representation of this Variable.

Specified by:

toString in class Variable

Returns:

A String representation of this Variable.
