Method Detail

activeHeuristic

public void activeHeuristic(boolean active)

setPad

public void setPad(int pad)

getMetaVariables

public ConstraintNetwork[] getMetaVariables()

Description copied from class: MetaConstraint

Get all MetaVariables according to this MetaConstraint. This method must be implemented by the designer of the implementing MetaConstraint class.

Specified by:

getMetaVariables in class MetaConstraint

Returns:

All MetaVariables according to this MetaConstraint.

isConflicting

protected boolean isConflicting(SymbolicVariableActivity[] peak,
                                java.util.HashMap<SymbolicVariableActivity,SpatialFluent> activityToFluent)

getMetaValues

public ConstraintNetwork[] getMetaValues(MetaVariable metaVariable)

Description copied from class: MetaConstraint

Get all meta values for a given MetaVariable. This method must be implemented in the specific MetaConstraint.

Specified by:

getMetaValues in class MetaConstraint

Parameters:

metaVariable - The MetaVariable for which we seek meta values.

Returns:

All meta values for the given MetaVariable.

markResolvedSub

public void markResolvedSub(MetaVariable metaVariable,
                            ConstraintNetwork metaValue)

Description copied from class: MetaConstraint

Method to mark a MetaVariable as solved. This method is called by the MetaConstraintSolver and must be implemented by the developer of the MetaConstraint.

Specified by:

markResolvedSub in class MetaConstraint

Parameters:

metaVariable - The MetaVariable that is to be considered solved by the given meta value.

metaValue - The solving meta value.

draw

public void draw(ConstraintNetwork network)

Description copied from class: MetaConstraint

Method to draw the metaCSP's constraint network according to the rationale of this MetaConstraint (e.g., for a resource, this could be the resource usage profile as it is determined by the given constraint network). This method must be implemented by the developer of the MetaConstraint.

Specified by:

draw in class MetaConstraint

Parameters:

network - The constraint network to draw.

toString

public java.lang.String toString()

Description copied from class: Constraint

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

Specified by:

toString in class Constraint

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.

clone

public java.lang.Object clone()

Specified by:

clone in class Constraint

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.

getGroundSolver

public ConstraintSolver getGroundSolver()

Description copied from class: MetaConstraint

Provides the definition of how to get the/a groundSolver for this MetaConstraint.

Specified by:

getGroundSolver in class MetaConstraint

Returns:

The/a groundSolver for this MetaConstraint.
