Method Details

objectType
Description copied from class:OntObjectImpl
Gets a public ont-object type identifier.- Specified by:
objectType
in interfaceOntObject
- Overrides:
objectType
in classOntObjectImpl
- Returns:
- Class, the actual type of this object
-
findRootStatement
Description copied from class:OntObjectImpl
Finds the first declaration root statement. The graph may contain several triples with predicaterdf:type
and this ontology object as a subject. In this case, the result is unpredictable.- Overrides:
findRootStatement
in classOntObjectImpl
- Returns:
- Optional around
OntStatement
that supports plain annotation assertions
-
superProperties
Description copied from interface:OntProperty
Answers aStream
over all the properties that are declared to be super-properties of this property. Each element of theStream
will have the same type as this property instance: if it is datatype property the method will return only data properties, etc. The parameterdirect
controls selectivity over the properties that appear in theStream
. Consider the following scenario:
(so:A rdfs:subPropertyOf :B . :A rdfs:subPropertyOf :C . :C rdfs:subPropertyOf :D .
A
has super-propertyB
andC
, andC
has super-propertyD
) In a raw model, with no inference support, listing the super-property ofA
will answerB
andC
. In an inferencing model,rdfs:subPropertyOf
is known to be transitive, so the super-property iterator will includeD
. Thedirect
super-properties are those members of the closure of the inverse-subPropertyOf relation, restricted to properties that cannot be reached by a longer route, i.e., the ones that are directly adjacent to the given root. Thus, the direct super-property ofA
areB
andC
only, and notD
- even in an inferencing graph. Note that this is different from the entailments from the raw graph. Suppose we add to this example:
Now, in the raw graph,:A rdfs:subPropertyOf :D .
A
has super-propertyB
,C
,D
. But the direct super-property ofA
remain onlyB
and C, since there is a longer pathA-C-D
that means thatD
is not a direct super-property ofA
. The assertion in the raw graph thatA
has super-propertyD
is essentially redundant, since this can be inferred from the closure of the graph.- Specified by:
superProperties
in interfaceOntProperty
- Parameters:
direct
-boolean
: iftrue
answers the directly adjacent properties in the super-property relation, i.e. eliminate any property for which there is a longer route to reach that parent under the super-property relation; iffalse
answers all super-properties found by inferencer, which usually means entire hierarchy up the tree; this instance is not included- Returns:
- distinct

- Parameters:

answers the directly adjacent properties in the sub-property relation: i.e. eliminate any properties for which there is a longer route to reach that parent under the sub-property relation; iffalse
answers all sub-properties found by inferencer, which usually means entire hierarchy down the tree; this property is not included- Returns:

Answers aStream
of all the classes in this ontology, such that each returned class has this property as one of its properties inOntClass.declaredProperties(boolean)
. This simulates a frame-like view of properties and classes; for more details see the Apache Jena: Presenting RDF as frames- Specified by:
declaringClasses
in interfaceOntProperty
- Parameters:
direct
-boolean
iftrue
, use only direct associations between classes and properties- Returns:
- a
Stream
of the classes having this property as one of their declared properties
-
hasSuperProperty
Description copied from interface:OntProperty
Answerstrue
if the given property is a super-property of this property. SeeOntProperty.superProperties(boolean)
for a full explanation of the direct parameter.- Specified by:
hasSuperProperty
in interfaceOntProperty
- Parameters:
property
- aOntProperty
to testdirect
-boolean
; If true, only search the properties that are directly adjacent to this property in the class hierarchy- Returns:
boolean

isBuiltIn
public boolean isBuiltIn()Description copied from interface:OntEntity
Determines if this is a builtin entity. In a standard (default) OWL2 vocabulary an entity is builtin if it is:- a
class
and its IRI is eitherowl:Thing
orowl:Nothing
- an
object property
and its IRI is eitherowl:topObjectProperty
orowl:bottomObjectProperty
- a
data property
and its IRI is eitherowl:topDataProperty
orowl:bottomDataProperty
- a
datatype
and its IRI is eitherrdfs:Literal
, orrdf:PlainLiteral
, or it is from the OWL 2 datatype map - an
annotation property
and its IRI is one of the following:rdfs:label
rdfs:comment
rdfs:seeAlso
rdfs:isDefinedBy
owl:deprecated
owl:versionInfo
owl:priorVersion
owl:backwardCompatibleWith
owl:incompatibleWith
Builtins Vocabulary
. A model with differentBuiltins
vocabulary will naturally have a differentSet
of builtin IRIs, and this method will return a different result. - a
-
getModel
OntModel getModel()Returns the ontology model associated with this resource. If the Resource was not created by a Model, the result may be null.- Specified by:
getModel
in interfaceorg.apache.jena.rdf.model.RDFNode
- Returns:
OntModel
-
isLocal
boolean isLocal()Determines if this Ontology Resource is locally defined. This means that the resource definition (i.e., a theroot statement
) belongs to the base ontology graph. If the ontology contains subgraphs (which should matchowl:imports
in OWL) and the resource is defined in one of them, than this method called from top-level interface will returnfalse
.- Returns:
true
if this resource is local to the base model graph.
-
getAs
Safely converts this RDF resource to the giventype
interface, if it is possible. Otherwise, returnsnull
. A calling of this method is effectively equivalent to the expressionthis.canAs(type) ? this.as(type) : null
.- Type Parameters:
X
- any subtype ofRDFNode
- Parameters:
type
- aClass
-type of the desired RDF view (interface)- Returns:
- an instance of the type
X
ornull
