Constructor Detail

PostulateEvaluator

public PostulateEvaluator(BeliefSetIterator<T,U> iterator,
                          PostulateEvaluatable<T> ev,
                          java.util.Collection<Postulate<T>> postulates)

Creates a new evaluator for the given evaluatable and belief base generator.

Parameters:

iterator - some belief set iterator

ev - some evaluatable

postulates - a set of postulates

PostulateEvaluator

public PostulateEvaluator(BeliefSetIterator<T,U> iterator,
                          PostulateEvaluatable<T> ev)

Creates a new evaluator for the given evaluatable and belief base generator.

Parameters:

iterator - some belief set iterator

ev - some evaluatable

Method Detail

addPostulate

public void addPostulate(Postulate<T> p)

Adds the given postulate

Parameters:

p - some postulate

addAllPostulates

public void addAllPostulates(java.util.Collection<? extends Postulate<T>> postulates)

Adds all postulates in the given collection.

Parameters:

postulates -

removePostulate

public boolean removePostulate(Postulate<T> p)

Removes the given postulate

Parameters:

p - some postulate

Returns:

true if this contained the specified postulate.

removeAllPostulates

public void removeAllPostulates(java.util.Collection<? extends Postulate<T>> postulates)

Removes all postulates in the given collection.

Parameters:

postulates -

evaluate

public PostulateEvaluationReport<T> evaluate(long num,
                                             boolean stopWhenFailed)

Evaluates all postulates of this evaluator on the given approach on num belief bases generated by the sampler of this evaluator.

Parameters:

num - the number of belief bases to be applied.

stopWhenFailed - if true the evaluation of one postulate will be stopped once a violation has been encountered.

Returns:

a report on the evaluation

evaluate

public PostulateEvaluationReport<T> evaluate(long num)

Evaluates all postulates of this evaluator on the given approach on num belief bases generated by the sampler of this evaluator. The evaluation of any one postulate will be stopped once a violation has been encountered.

Parameters:

num - the number of belief bases to be applied.

Returns:

a report on the evaluation
