Interface Triple

All Superinterfaces:

Resource, Serializable, Value

All Known Implementing Classes:

AbstractTriple, MemTriple, SimpleTriple

@Experimental
public interface Triple
extends Resource

An RDF* embedded triple. Embedded triples have a subject, predicate and object. Unlike Statement, a triple never has an associated context.

Additional utility functionality for working with Triple objects is available in the org.eclipse.rdf4j.model.util.Statements utility class.

Method Detail

isTriple

default boolean isTriple()

Description copied from interface: Value

Check if the object is an instance of the given type. Typically 2x than using instanceof. For implementers: This default implementation is overridden in the repsective sub-interface.

Specified by:

isTriple in interface Value

Returns:

true if instance of Triple

getSubject

Resource getSubject()

Gets the subject of this triple.

Returns:

The triple's subject.

getPredicate

IRI getPredicate()

Gets the predicate of this triple.

Returns:

The triple's predicate.

getObject

Value getObject()

Gets the object of this triple.

Returns:

The triple's object.

equals

boolean equals(Object other)

Compares this triple to another object.

Overrides:

equals in class Object

Parameters:

other - 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

int hashCode()

Computes the hash code of this triple.

Overrides:

hashCode in class Object

Returns:

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