Constructor Detail

SimpleTriple

protected SimpleTriple(Resource subject,
                       IRI predicate,
                       Value object)

Creates a new Triple with the supplied subject, predicate and object.

Note that creating SimpleStatement objects directly via this constructor is not the recommended approach. Instead, use an instance of ValueFactory to create new Triple objects.

Parameters:

subject - The triple's subject, must not be null.

predicate - The triple's predicate, must not be null.

object - The triple's object, must not be null.

The triple's predicate.

getObject

public Value getObject()

Gets the object of this triple.

Specified by:

getObject in interface Triple

Specified by:

equals in interface Triple

Overrides:

equals in class Object

Parameters:

o - the object to compare this triple to

Returns:

true if the other object is an instance of Triple and if their subjects, predicates and objects are equal; false otherwise

hashCode

public int hashCode()

Description copied from interface: Triple

Computes the hash code of this triple.

Specified by:

hashCode in interface Triple

hashCode in class Object

Returns:

a hash code for this triple computed as Objects.hash( Triple.getSubject(), Triple.getPredicate(), Triple.getObject())
