Represents an OWL 2 Ontology in the OWL 2 specification.
An OWLOntology consists of a possibly empty set of OWLAxioms and a possibly empty set of OWLAnnotations. An ontology can have an ontology IRI which can be used to identify the ontology. If it has an ontology IRI then it may also have an ontology version IRI. Since OWL 2, an ontology need not have an ontology IRI. (See the OWL 2 Structural Specification An ontology cannot be modified directly. Changes must be applied via its OWLOntologyManager.

  - getAnnotations
```
Set<OWLAnnotation> getAnnotations()
```
    Gets the annotations on this ontology.
    
    Returns:
    A set of annotations on this ontology. The set returned will be a copy - modifying the set will have no effect on the annotations in this ontology, similarly, any changes that affect the annotations on this ontology will not change the returned set.
  - getDirectImportsDocuments

```
    Gets the set of loaded ontologies that this ontology is related to via the directlyImports relation. See Section 3.4 of the OWL 2 specification for the definition of the directlyImports relation.
    Note that there may be fewer ontologies in the set returned by this method than there are IRIs in the set returned by the getDirectImportsDocuments() method. This will be the case if some of the ontologies that are directly imported by this ontology are not loaded for whatever reason.
    
    Returns:
    A set of ontologies such that for this ontology O, and each ontology O' in the set, (O, O') is in the directlyImports relation.

    Returns:
    The set of ontologies that this ontology is related to via the transitive closure of the directlyImports relation. The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.

    UnknownOWLOntologyException - if this ontology is no longer managed by its manager because it was removed from the manager.
  - getImportsClosure

```
    Gets the set of loaded ontologies that this ontology is related to via the reflexive transitive closure of the directlyImports relation as defined in Section 3.4 of the OWL 2 Structural Specification. (i.e. The set returned includes all ontologies returned by the getImports() method plus this ontology.)
    For example, if this ontology imports ontology B, and ontology B imports ontology C, then this method will return the set consisting of this ontology, ontology B and ontology C.
    
    Returns:
    The set of ontologies in the reflexive transitive closure of the directlyImports relation.

    The set of imports declarations that correspond to the set of ontology document IRIs that are directly imported by this ontology. The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
  - isEmpty
```
boolean isEmpty()
```
    Determines if this ontology is empty - an ontology is empty if it does not contain any axioms (i.e. getAxioms() returns the empty set), and it does not have any annotations (i.e. getAnnotations() returns the empty set).
    
    Returns:
    true if the ontology is empty, otherwise false.
  - getAxioms
```
Set<OWLAxiom> getAxioms()
```
    Retrieves all of the axioms in this ontology. Note that to test whether or not this ontology is empty (i.e. contains no axioms, the isEmpty method is preferred over getAxioms().isEmpty(). )
    
    Returns:
    The set of all axioms in this ontology, including logical axioms and annotation axioms. The set that is returned is a copy of the axioms in the ontology - it will not be updated if the ontology changes. It is recommended that the containsAxiom method is used to determine whether or not this ontology contains a particular axiom rather than using getAxioms().contains().

Set<OWLObjectPropertyAssertionAxiom> getObjectPropertyAssertionAxioms(OWLIndividual individual)
```
    Gets the OWLObjectPropertyAssertionAxioms contained in this ontology that have the specified individual as the subject of the axiom.
    
    Parameters:
    individual - The individual that the returned axioms have as a subject.
    
    Returns:
    A set of OWLObjectPropertyAssertionAxiom s such that each axiom in the set is of the form ObjectPropertyAssertion(dp, individual, obj) (for each axiom OWLPropertyAssertionAxiom.getSubject() is equal to individual). The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
  - getNegativeObjectPropertyAssertionAxioms
```
Set<OWLNegativeObjectPropertyAssertionAxiom> getNegativeObjectPropertyAssertionAxioms(OWLIndividual individual)
```
    Gets the OWLNegativeObjectPropertyAssertionAxiom s contained in this ontology that have the specified individual as the subject of the axiom.
    
    Parameters:
    individual - The individual that the returned axioms have as a subject.
    
    Returns:
    A set of OWLNegativeObjectPropertyAssertionAxiom s such that each axiom in the set is of the form NegativeObjectPropertyAssertion(dp, individual, obj) (for each axiom OWLPropertyAssertionAxiom.getSubject() is equal to individual). The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
  - getNegativeDataPropertyAssertionAxioms
```
Set<OWLNegativeDataPropertyAssertionAxiom> getNegativeDataPropertyAssertionAxioms(OWLIndividual individual)
```
    Gets the OWLNegativeDataPropertyAssertionAxiom s contained in this ontology that have the specified individual as the subject of the axiom.
    
    Parameters:
    individual - The individual that the returned axioms have as a subject.
    
    Returns:
    A set of OWLNegativeDataPropertyAssertionAxiom s such that each axiom in the set is of the form NegativeDataPropertyAssertion(dp, individual, obj) (for each axiom OWLPropertyAssertionAxiom.getSubject() is equal to individual). The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
  - getSameIndividualAxioms
```
Set<OWLSameIndividualAxiom> getSameIndividualAxioms(OWLIndividual individual)
```
    Gets the OWLSameIndividualAxioms contained in this ontology that make the specified individual the same as some other individual.
    
    Parameters:
    individual - The individual that the returned axioms make the same as some other individual.
    
    Returns:
    A set of OWLSameIndividualAxioms such that each axiom in the set is of the form SameIndividual(individual, ind, ...) (for each axiom returned OWLNaryIndividualAxiom.getIndividuals() contains individual. The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
  - getDifferentIndividualAxioms
```
Set<OWLDifferentIndividualsAxiom> getDifferentIndividualAxioms(OWLIndividual individual)
```
    Gets the OWLDifferentIndividualsAxioms contained in this ontology that make the specified individual different to some other individual.
    
    Parameters:
    individual - The individual that the returned axioms make the different as some other individual.
    
    Returns:
    A set of OWLDifferentIndividualsAxiom s such that each axiom in the set is of the form DifferentIndividuals(individual, ind, ...) (for each axiom returned OWLNaryIndividualAxiom.getIndividuals() contains individual. The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
  - getDatatypeDefinitions
```
Set<OWLDatatypeDefinitionAxiom> getDatatypeDefinitions(OWLDatatype datatype)
```
    Gets the OWLDatatypeDefinitionAxioms contained in this ontology that provide a definition for the specified datatype.
    
    Parameters:
    datatype - The datatype for which the returned axioms provide a definition.
    
    Returns:
    A set of OWLDatatypeDefinitionAxioms such that for each axiom in the set OWLDatatypeDefinitionAxiom.getDatatype() is equal to datatype. The set that is returned is a copy - it will not be updated if the ontology changes. It is therefore safe to apply changes to this ontology while iterating over this set.
