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.

Method Detail

getSubject

public Resource getSubject()

Description copied from interface: Triple

Gets the subject of this triple.

Returns:

The triple's subject.

getPredicate

public IRI getPredicate()

Description copied from interface: Triple

Gets the predicate of this triple.

Returns:

The triple's predicate.

getObject

public Value getObject()

Description copied from interface: Triple

Gets the object of this triple.

Returns:

The triple's object.

stringValue

public String stringValue()

Description copied from interface: Value

Returns the String-value of a Value object. This returns either a Literal's label, a IRI's URI or a BNode's ID.

Specified by:

stringValue in interface Value

Overrides:

stringValue in class AbstractTriple

toString

public String toString()

Overrides:

toString in class AbstractTriple

equals

public boolean equals(Object o)

Description copied from interface: Triple

Compares this triple to another object.

Specified by:

equals in interface Triple

Overrides:

equals in class AbstractTriple

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

Overrides:

hashCode in class AbstractTriple

Returns:

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