Constructor Detail

AbstractOWLMetric

public AbstractOWLMetric(OWLOntology o)

Instantiates a new abstract owl metric.

Parameters:

o - the ontology to use

Method Detail

getOntology

public OWLOntology getOntology()

Description copied from interface: OWLMetric

Gets the ontology which the value of the metric should be based on.

Specified by:

getOntology in interface OWLMetric<M extends Serializable>

Returns:

The ontology.

setOntology

public void setOntology(OWLOntology ontology)

Description copied from interface: OWLMetric

Sets the "root" ontology. The metric will be recomputed from this ontology (and potentially its imports closure if selected).

Specified by:

setOntology in interface OWLMetric<M extends Serializable>

Parameters:

ontology - The ontology for which the metric should be computed.

getValue

public M getValue()

Description copied from interface: OWLMetric

Gets the value of this metric. This value is computed w.r.t. the current ontology and possibly the imports closure (if specified).

Specified by:

getValue in interface OWLMetric<M extends Serializable>

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.

getOntologies

public java.util.stream.Stream<OWLOntology> getOntologies()

Gets the ontologies.

Returns:

ontologies as a set

ontologiesChanged

public void ontologiesChanged(List<? extends OWLOntologyChange> changes)

Specified by:

ontologiesChanged in interface OWLOntologyChangeListener

getManager

public OWLOntologyManager getManager()

Description copied from interface: OWLMetric

Gets the ontology manager which, amongst other things can be used to obtain the imports closure of the current ontology.

Specified by:

getManager in interface OWLMetric<M extends Serializable>

Returns:

An OWLOntologyManager.

dispose

public void dispose()

Description copied from interface: OWLMetric

Diposes 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.

Specified by:

dispose in interface OWLMetric<M extends Serializable>

isImportsClosureUsed

public boolean isImportsClosureUsed()

Description copied from interface: OWLMetric

Determines if the computation of the metric should take into account the imports closure of the current ontology.

Specified by:

isImportsClosureUsed in interface OWLMetric<M extends Serializable>

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

public void setImportsClosureUsed(boolean b)

Description copied from interface: OWLMetric

Sets whether this metric uses the imports closure of the current ontology.

Specified by:

setImportsClosureUsed in interface OWLMetric<M extends Serializable>

Parameters:

b - the new imports closure used true if this metric uses the imports closure of the current ontology, otherwise false.

toString

public String toString()

Overrides:

toString in class Object
