All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class FuzzyActivityDomain
extends MetaConstraint

Implements the MetaConstraint for fuzzy context recognition. Variable of the the meta-CSP are rules in a so-called "domain" (this class), and values are unifications of the requirements prescribed by these rules with existing FuzzyActivity variables.

Constructor Detail

FuzzyActivityDomain

public FuzzyActivityDomain()

Creates a new FuzzyActivityDomain. Rules should then be added to the instantiated domain.

Method Detail

setRuleDependency

public void setRuleDependency()

IRAN: can you make this private or protected?

setUnjustified

public void setUnjustified(ConstraintNetwork metaVariable)

Sets all Variables underlying a MetaVariable to the UNJUSTIFIED state.

Parameters:

metaVariable -

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.

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 con,
                            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:

con - 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.

addRule

public void addRule(Rule r)

Add a Rule to this MetaConstraint.

Parameters:

r - The rule to add.

getRules

public Rule[] getRules()

Get all rules in this MetaConstraint.

Returns:

All rules in this MetaConstraint.

addFuzzySensorEvents

public void addFuzzySensorEvents(FuzzySensorEvent... events)

Add one or more sensor events to this MetaConstraint.

Parameters:

events - The events to add.

getConsitency

public double getConsitency()

Get the upper bound on the overall (temporal + value) consistency of the ConstraintNetwork.

Returns:

Upper bound on the overall (temporal + value) consistency of the ConstraintNetwork.

getConstraintNetwork

public ConstraintNetwork getConstraintNetwork()

Get the ConstraintNetwork used by the meta-CSP's FuzzyActivityNetworkSolver.

Returns:

The ConstraintNetwork used by the meta-CSP.

getFalseClause

public java.util.Vector<Constraint> getFalseClause()

IRAN: please comment this.

Returns:

IRAN: please comment this.

resetFalseClause

public void resetFalseClause()

IRAN: please comment this.

getOptimalHypothesis

public java.lang.String getOptimalHypothesis(ConstraintNetwork optCn,
                                             double vc,
                                             double tc)

getValueConsistency

public double getValueConsistency()

getTemporalConsistency

public double getTemporalConsistency()

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:

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()
