Constructor Details

SimpleTripleTerm

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

Creates a new TripleTerm 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 TripleTerm 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 Details

getSubject

public Resource getSubject()

Description copied from interface: TripleTerm

Gets the subject of this triple.

Returns:

The triple's subject.

getPredicate

public IRI getPredicate()

Description copied from interface: TripleTerm

Gets the predicate of this triple.

Returns:

The triple's predicate.

getObject

public Value getObject()

Description copied from interface: TripleTerm

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 AbstractTripleTerm

toString

public String toString()

Overrides:

toString in class AbstractTripleTerm

equals

public boolean equals(Object o)

Description copied from interface: TripleTerm

Compares this triple to another object.

Specified by:

equals in interface TripleTerm

Overrides:

equals in class AbstractTripleTerm

Parameters:

o - the object to compare this triple to

Returns:

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

hashCode

public int hashCode()

Description copied from interface: TripleTerm

Computes the hash code of this triple.

Specified by:

hashCode in interface TripleTerm

Overrides:

hashCode in class AbstractTripleTerm

Returns:

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