public interface OWLDocumentFormat
extends Serializable

Represents the concrete representation format of an ontology. The equality of an ontology format is defined by the equals and hashCode method (not its identity).

2.0.0

Method Detail

isMissingType

static boolean isMissingType(OWLEntity entity,
                             OWLOntology ontology)

Determines if a declaration axiom (type triple) needs to be added to the specified ontology for the given entity.

Parameters:

entity - The entity

ontology - The ontology.

Returns:

false if the entity is built in. false if the ontology doesn't contain the entity in its signature. false if the entity is already declared in the imports closure of the ontology. false if the transitive imports does not contain the ontology but the entity is contained in the signature of one of the imported ontologies, true if none of the previous conditions are met.

determineIllegalPunnings

static Collection<IRI> determineIllegalPunnings(boolean add,
                                                Stream<OWLEntity> signature,
                                                Collection<IRI> punnedEntities)

Parameters:

signature - signature for the ontology

punnedEntities - the set of entities that are known already to be punned

add - true if missing declarations should be added. If false, no declarations will be added.

Returns:

collection of IRIS used in illegal punnings

computeIllegals

static Collection<IRI> computeIllegals(com.google.common.collect.Multimap<IRI,EntityType<?>> punnings)

Parameters:

punnings - input punnings

Returns:

illegal punnings

isAddMissingTypes

boolean isAddMissingTypes()

Determines if untyped entities should automatically be typed (declared) during rendering. (This is a hint to an RDF renderer - the reference implementation will respect this).

Returns:

true if untyped entities should automatically be typed during rendering, otherwise false.

setAddMissingTypes

void setAddMissingTypes(boolean addMissingTypes)

Determines if untyped entities should automatically be typed during rendering. By default this is true.

Parameters:

addMissingTypes - true if untyped entities should automatically be typed during rendering, otherwise false.

setParameter

void setParameter(Serializable key,
                  Serializable value)

Parameters:

key - key for the new entry

value - value for the new entry

getParameter

<T> T getParameter(Serializable key,
                   T defaultValue)

Type Parameters:

T - type

Parameters:

key - key for the new entry

defaultValue - value for the new entry

Returns:

the value

isPrefixOWLDocumentFormat

default boolean isPrefixOWLDocumentFormat()

Determines if this format is an instance of a format that uses prefixes to shorted IRIs.

Returns:

true if this format is an instance of PrefixDocumentFormat other wise false.

asPrefixOWLDocumentFormat

default PrefixDocumentFormat asPrefixOWLDocumentFormat()

If this format is an instance of PrefixDocumentFormat then this method will obtain it as a PrefixDocumentFormat.

Returns:

This format as a more specific PrefixDocumentFormat.

Throws:

ClassCastException - if this format is not an instance of PrefixDocumentFormat

getOntologyLoaderMetaData

Optional<OWLOntologyLoaderMetaData> getOntologyLoaderMetaData()

If this format describes an ontology that was loaded from some ontology document (rather than created programmatically) there may be some meta data about the loading process. Subclasses of OWLDocumentFormat will provide accessors etc. to details pertaining to the meta data about loading.

Returns:

An object containing the meta data about loading. .

setOntologyLoaderMetaData

void setOntologyLoaderMetaData(OWLOntologyLoaderMetaData loaderMetaData)

Sets the meta data for the ontology loader.

Parameters:

loaderMetaData - The metadata.

Throws:

NullPointerException - if the loaderMetaData is null.

getKey

String getKey()

Returns:

A unique key for this format.

isTextual

boolean isTextual()

Determines whether this format contains textual output, as opposed to binary output.

Returns:

True if this format represents a textual format, as opposed to a binary format. Defaults to true if not overridden.
