Methods

Modifier and Type	Method and Description
boolean	equals(Object obj)
Resource	getObject()
UriRef	getPredicate()
NonLiteral	getSubject()
int	hashCode() The hash code is computed as follow (subject.hashCode() >> 1) ^ predicate.hashCode() ^ object.hashCode() << 1) Note that the hash returned is computed including the hash of BNodes, so it is not blank-node blind as in Graph.

Constructor Detail

TripleImpl

public TripleImpl(NonLiteral subject,
          UriRef predicate,
          Resource object)

Creates a new TripleImpl.

Parameters:

subject - the subject.

predicate - the predicate.

object - the object.

Throws:

IllegalArgumentException - if an attribute is null.

Method Detail

equals

public boolean equals(Object obj)

Specified by:

equals in interface Triple

Overrides:

equals in class Object

Returns:

true iff subject, predicate, and object of both triples are equal

hashCode

public int hashCode()

Description copied from interface: Triple

The hash code is computed as follow (subject.hashCode() >> 1) ^ predicate.hashCode() ^ object.hashCode() << 1) Note that the hash returned is computed including the hash of BNodes, so it is not blank-node blind as in Graph. This would have to change if triple should extend Graph

Specified by:

hashCode in interface Triple

Overrides:

hashCode in class Object

Returns:

hash code

getSubject

public NonLiteral getSubject()

Specified by:

getSubject in interface Triple

getPredicate

public UriRef getPredicate()

Specified by:

getPredicate in interface Triple

getObject

public Resource getObject()

Specified by:

getObject in interface Triple

toString

public String toString()

Overrides:

toString in class Object
