Annotations are used in the various types of annotation axioms, which bind annotations to their subjects (i.e. axioms or declarations). An annotation is equal to another annotation if both objects have equal annotation URIs and have equal annotation values

Method Summary

void	accept(OWLAnnotationVisitor visitor)
<O> O	accept(OWLAnnotationVisitorEx<O> visitor)
java.net.URI	getAnnotationURI() Gets the annotation URI
O	getAnnotationValue() Gets the annotation value.
OWLConstant	getAnnotationValueAsConstant() If this is a constant annotation (rather than an entity annotation) then this convenience method obtains the annoation value as a constant.
boolean	isAnnotationByConstant() Determines if the annotation value is a constant.

Method Detail

getAnnotationURI

java.net.URI getAnnotationURI()

Gets the annotation URI

isAnnotationByConstant

boolean isAnnotationByConstant()

Determines if the annotation value is a constant.

Returns:

true if the annotation value is a constant, or false if the annotation value is an entity (class, property, individual or datatype)

getAnnotationValue

O getAnnotationValue()

Gets the annotation value. The type of value will depend upon the type of the annotation e.g. whether the annotation is a constant annotation, individual annotation etc.

getAnnotationValueAsConstant

OWLConstant getAnnotationValueAsConstant()

If this is a constant annotation (rather than an entity annotation) then this convenience method obtains the annoation value as a constant. Calling this method if the isAnnotationByConstant method returns false will throws an OWLRuntimeException

accept

void accept(OWLAnnotationVisitor visitor)

accept

<O> O accept(OWLAnnotationVisitorEx<O> visitor)
