Class SimpleAllenInterval

java.lang.Object

org.metacsp.framework.Variable

org.metacsp.time.qualitative.SimpleAllenInterval

All Implemented Interfaces:

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

public class SimpleAllenInterval
extends Variable

An implementation of the Allen interval variable. This implementation is different from AllenInterval, which is a MultiVariable representing an interval as two timepoints. This implementation is used for qualitative temporal reasoning (e.g., with the FuzzyAllenIntervalNetworkSolver), whereas the AllenInterval is used for quantitative temporal reasoning (e.g., by the AllenIntervalNetworkSolver).

                           int id)

Method Detail

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.

compareTo

public int compareTo(Variable arg0)

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.
