Method Detail

getInstance

public static OWLOntologyDictionary getInstance()

Threadsafe method to get the single instance of this class.

Since:

1.1.0

put

public void put(OWLOntology ontology)

Adds the given OWLOntology to the mapping using its default document URI. Generates a mapping of all contained OWLEntity instances to their IDs. If OWLEntity instances are added or removed this mapping will not be updated. It is recommended to reintroduce the OWLOntology to the OWLOntologyDictionary. TODO Can this be automatised by using the OWLAPI ChangeListener?

Since:

1.1.0

get

public OWLOntology get(URI source)

Returns the OWLOntology corresponding to the given URI.

Returns:

The corresponding URI or null if nothing could be found.

getEntity

public OWLEntity getEntity(Integer id)

getEntity.

Returns:

The corresponding OWLEntity or null if nothing could be found.

getID

public Integer getID(OWLEntity entity)
              throws IllegalArgumentException

getID.

Returns:

The corresponding id

Throws:

IllegalArgumentException - Is thrown if the OWLEntity could not be found or is null.

remove

public void remove(OWLOntology ontology)

Removes the given OWLOntology and all contained OWLEntity instances from this OWLOntologyDictionary.

Parameters:

ontology - OWLOntology to remove.
