  • Method Summary

    Modifier and Type
    Method
    Description
    void
    dispose()
    Disposes of the metric.
    OWLOntologyManager
    getManager()
    Gets the ontology manager which, amongst other things can be used to obtain the imports closure of the current ontology.
    String
    getName()
    Gets the human readable name of this metric.
    OWLOntology
    getOntology()
    Gets the ontology which the value of the metric should be based on.
    M
    getValue()
    Gets the value of this metric.
    boolean
    isImportsClosureUsed()
    Determines if the computation of the metric should take into account the imports closure of the current ontology.
    void
    setImportsClosureUsed(boolean b)
    Sets whether this metric uses the imports closure of the current ontology.
    void
    setOntology(OWLOntology ontology)
    Sets the "root" ontology.

  • Method Details

    • getName

      String getName()
      Gets the human readable name of this metric.
      Returns:
      A label which represents the human readable name of this metric.

    • getValue

      M getValue()
      Gets the value of this metric. This value is computed w.r.t. the current ontology and possibly the imports closure (if specified).
      Returns:
      An object which represents the value of this metric - calling the toString method of the object returned by this method will result in a human readable string that displays the value of the metric.

    • getOntology

      OWLOntology getOntology()
      Gets the ontology which the value of the metric should be based on.
      Returns:
      The ontology.

    • setOntology

      void setOntology(OWLOntology ontology)
      Sets the "root" ontology. The metric will be recomputed from this ontology (and potentially its imports closure if selected).
      Parameters:
      ontology - The ontology for which the metric should be computed.

    • isImportsClosureUsed

      boolean isImportsClosureUsed()
      Determines if the computation of the metric should take into account the imports closure of the current ontology.
      Returns:
      true if the imports closure of the current ontology is taken into account when computing the value of this metric, or false if the imports closure isn't taken into account when computing this metric.

    • setImportsClosureUsed

      void setImportsClosureUsed(boolean b)
      Sets whether this metric uses the imports closure of the current ontology.
      Parameters:
      b - the new imports closure used true if this metric uses the imports closure of the current ontology, otherwise false.

    • getManager

      OWLOntologyManager getManager()
      Gets the ontology manager which, amongst other things can be used to obtain the imports closure of the current ontology.
      Returns:
      An OWLOntologyManager.

    • dispose

      void dispose()
      Disposes of the metric. If the metric attaches itself as a listener to an ontology manager then this will cause the metric to detach itself and stop listening for ontology changes.
