                   Term predicate)

Triple.Impl

public Triple.Impl(Term subject,
                   Term object,
                   Term predicate,
                   String name,
                   String description)

Method Detail

getName

public String getName()

Description copied from interface: Term

Return the name of this term.

Specified by:

getName in interface Term

getDescription

public String getDescription()

Description copied from interface: Term

Return a human-readable description of this term, or the empty string if none is available.

Specified by:

getDescription in interface Term

getOntology

public Ontology getOntology()

Description copied from interface: Term

Return the ontology in which this term exists.

Specified by:

getOntology in interface Term

getSubject

public Term getSubject()

Description copied from interface: Triple

Return the subject term of this triple

Specified by:

getSubject in interface Triple

getObject

public Term getObject()

Description copied from interface: Triple

Return the object term of this triple.

Specified by:

getObject in interface Triple

getPredicate

public Term getPredicate()

Description copied from interface: Triple

Return a Term which defines the type of relationship between the subject and object terms.

Specified by:

getPredicate in interface Triple

getAnnotation

public Annotation getAnnotation()

Description copied from interface: Annotatable

Should return the associated annotation object.

Specified by:

getAnnotation in interface Annotatable

Returns:

an Annotation object, never null

equals

public boolean equals(Object o)

Two triples are equal if all their fields are identical.

Specified by:

equals in interface Triple

hashCode

public int hashCode()

Description copied from interface: Triple

The hashcode for a Triple.

This must be implemented as:

 return getSubject().hashCode() +
   31 * getObject().hashCode() +
   31 * 31 * getPredicate().hashCode();
 

If you do not implement hashcode in this way then you have no guarantee that your Triple objects will be found in an ontology and that they will not be duplicated.

Specified by:

hashCode in interface Triple

toString

public String toString()
