Method Detail

getAnnotations

java.util.Set<Annotation> getAnnotations(Ontology ontology)
                                         throws KAON2Exception

Returns the set of annotations of this entity.

Parameters:

ontology - the ontology in which the search is perfromed

Returns:

the set of annotations

Throws:

KAON2Exception - thrown if there is an error

getAnnotationValues

java.util.Map<AnnotationProperty,java.util.Set<java.lang.Object>> getAnnotationValues(Ontology ontology)
                                                                                      throws KAON2Exception

Returns the set of annotations of this entity grouped by annotation properties.

Parameters:

ontology - the ontology in which the search is perfromed

Returns:

the value of annotations grouped by annotation properties

Throws:

KAON2Exception - thrown if there is an error

getAnnotationValues

java.util.Set<java.lang.Object> getAnnotationValues(Ontology ontology,
                                                    AnnotationProperty annotationProperty)
                                                    throws KAON2Exception

Returns the set of annotation values of this entity for given annotation property.

Parameters:

ontology - the ontology in which the search is perfromed

annotationProperty - the annotation property

Returns:

the values of annotations with given annotation property

Throws:

KAON2Exception - thrown if there is an error

getAnnotationValue

java.lang.Object getAnnotationValue(Ontology ontology,
                                    AnnotationProperty annotationProperty)
                                    throws KAON2Exception

Returns the value of annotation for given annotation property. If there are multiple values, one is returned arbitrarily. If there are no values, null is returned. Note that this method does allow for distinguishing "no value" from "null-value" situations.

Parameters:

ontology - the ontology in which the search is perfromed

annotationProperty - the annotation property

Returns:

the value of annotations with given annotation property

Throws:

KAON2Exception
