Method Details

asStatement

public org.eclipse.rdf4j.model.Statement asStatement()

Description copied from interface: RDF4JTripleLike

Return the corresponding RDF4J Statement.

Specified by:

asStatement in interface RDF4JTripleLike

Returns:

The corresponding RDF4J Statement.

equals

public boolean equals(Object obj)

Description copied from interface: Triple

Check it this Triple is equal to another Triple.

Two Triples are equal if and only if their Triple.getSubject(), Triple.getPredicate() and Triple.getObject() are equal.

Implementations MUST also override Triple.hashCode() so that two equal Triples produce the same hash code.

Specified by:

equals in interface Triple

Overrides:

equals in class Object

Parameters:

obj - Another object

Returns:

true if other is a Triple and is equal to this

See Also:

• Object.equals(Object)

getObject

public RDFTerm getObject()

Description copied from interface: Triple

The object of this triple, which may be either a BlankNode, an IRI, or a Literal, which are represented in Commons RDF by the interface RDFTerm.

Specified by:

getObject in interface Triple

Specified by:

getObject in interface TripleLike

Returns:

The object RDFTerm of this triple.

See Also:

• RDF-1.1 Triple object

getPredicate

public IRI getPredicate()

Description copied from interface: Triple

The predicate IRI of this triple.

Specified by:

getPredicate in interface Triple

Specified by:

getPredicate in interface TripleLike

Returns:

The predicate IRI of this triple.

See Also:

• RDF-1.1 Triple predicate

getSubject

public BlankNodeOrIRI getSubject()

Description copied from interface: Triple

The subject of this triple, which may be either a BlankNode or an IRI, which are represented in Commons RDF by the interface BlankNodeOrIRI.

Specified by:

getSubject in interface Triple

Specified by:

getSubject in interface TripleLike

Returns:

The subject BlankNodeOrIRI of this triple.

See Also:

• RDF-1.1 Triple subject

hashCode

public int hashCode()

Description copied from interface: Triple

Calculate a hash code for this Triple.

The returned hash code MUST be equal to the result of Objects.hash(Object...) with the arguments Triple.getSubject(), Triple.getPredicate(), Triple.getObject().

This method MUST be implemented in conjunction with Triple.equals(Object) so that two equal Triples produce the same hash code.

Specified by:

hashCode in interface Triple

Overrides:

hashCode in class Object

Returns:

a hash code value for this Triple.

See Also:

• Object.hashCode()
• Objects.hash(Object...)

toString

public String toString()

Overrides:

toString in class Object
