AlternativeEvaluations

public AlternativeEvaluations()

AlternativeEvaluations

public AlternativeEvaluations(Map<Criterion,Double> evaluations)

Iteration order of the given evaluations is kept: this is used in the toString() method, for debug.

Parameters:

evaluations - not null.

Method Detail

getEvaluations

public Map<Criterion,Double> getEvaluations()

Returns:

the evaluations contained in this object. Not null. Can also be used to modify this object's evaluations.

getEvaluation

public Double getEvaluation(Criterion criterion)

Parameters:

criterion - not null.

Returns:

null iff no evaluation is defined for that criterion (i.e. that criterion is not contained in this object).

putEvaluation

public Double putEvaluation(Criterion criterion,
                            Double evaluation)

Parameters:

criterion - not null.

evaluation - null to remove the evaluation associated to the given criterion.

Returns:

the previous evaluation associated to this criterion, or null if there was none.

setOrder

public void setOrder(Set<Criterion> critsOrder)

Sets the order on which the criteria are enumerated when using the toString() method. If other criteria are added afterwards to this object, the order is not defined.

Parameters:

critsOrder - will be iterated over, thus should be ordered (a SortedSet or a LinkedHashSet may be used, e.g.). Must contain exactly the same set of criteria this object contains evaluations for.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

dominates

public boolean dominates(AlternativeEvaluations target)
                  throws InvalidInputException

Parameters:

target - must be evaluated on the same criteria set than this object.

Returns:

true iff this object strictly dominates the given one.

Throws:

InvalidInputException - iff a preference direction is unknown.
