public class SpatioTemporalVariable
extends MultiVariable

A SpatioTemporalVariable is a MultiVariable composed of an AllenInterval (temporal part) and a GeometricShapeVariable (spatial part). Constraints of type AllenIntervalConstraint and DE9IMRelation can be added to SpatioTemporalVariables.

SpatioTemporalVariable

public SpatioTemporalVariable(ConstraintSolver cs,
                              int id,
                              ConstraintSolver[] internalSolvers,
                              Variable[] internalVars)

Method Detail

compareTo

public int compareTo(Variable o)

createInternalConstraints

protected Constraint[] createInternalConstraints(Variable[] variables)

Description copied from class: MultiVariable

This method must be implemented to define the internal lower-level Constraints of this MultiVariable.

Specified by:

createInternalConstraints in class MultiVariable

Parameters:

variables - The internal variables among which the Constraints should be defined.

Returns:

The internal lower-level Constraints of this MultiVariable.

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.

getTemporalVariable

public AllenInterval getTemporalVariable()

Returns the temporal part of this SpatioTemporalVariable.

Returns:

An AllenInterval representing the temporal part of this SpatioTemporalVariable.

getSpatialVariable

public GeometricShapeVariable getSpatialVariable()

Returns the spatial part of this SpatioTemporalVariable.

Returns:

A GeometricShapeVariable representing the spatial part of this SpatioTemporalVariable.
