Method Detail

inconsistencyMeasure

public abstract java.lang.Double inconsistencyMeasure(java.util.Collection<S> formulas)

Description copied from class: BeliefSetInconsistencyMeasure

This method measures the inconsistency of the given set of formulas.

Specified by:

inconsistencyMeasure in class BeliefSetInconsistencyMeasure<S extends Formula>

Parameters:

formulas - a collection of formulas.

Returns:

a Double indicating the degree of inconsistency.

getInconsistencyMeasureProcess

public abstract InconsistencyMeasurementProcess<S> getInconsistencyMeasureProcess(FormulaStream<S> stream)

Processes the formulas in the given stream one after the other. After each update an event of type "InconsistencyUpdateEvent" is created and listeners are notified. This method creates and starts a new object of type "InconsistencyMeasurementProcess" that processes the stream in a separate thread, and returns it. The current value of inconsistency can be retrieved by the "getInconsistencyValue()" of that process and measurement can be aborted by calling its "abort()" method.

Parameters:

stream - some formula stream.

Returns:

an inconsistency measurement process.

addInconsistencyListener

public abstract void addInconsistencyListener(InconsistencyListener listener)

Add a listener to this measure.

Parameters:

listener - the listener to be added.

removeInconsistencyListener

public abstract void removeInconsistencyListener(InconsistencyListener listener)

Remove a listener from this measure.

Parameters:

listener - the listener to be removed.

fireInconsistencyUpdateEvent

abstract void fireInconsistencyUpdateEvent(InconsistencyUpdateEvent evt)

This method is called by inconsistency measurement processes to dispatch events to listeners.

Parameters:

evt - some event to be fired.

fireInconsistencyMeasurementStartedEvent

abstract void fireInconsistencyMeasurementStartedEvent(InconsistencyUpdateEvent evt)

This method is called by inconsistency measurement processes to dispatch an event about inconsistency measurement starts to listeners.

Parameters:

evt - some event to be fired.
