  • Method Details

    • inconsistencyMeasure

      public abstract Double inconsistencyMeasure(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.
