       RdfTerm object)

Method Detail

of

public static RdfTriple of(RdfResource subject,
                           RdfResource predicate,
                           RdfTerm object)

subject

public RdfResource subject()

Description copied from interface: RdfTriple

Returns the subject of the triple.

The subject is either an absolute IRI or a blank node identifier, denoting the resource being described by the statement.

Specified by:

subject in interface RdfTriple

Returns:

a RdfResource representing the subject of the triple; never null

predicate

public RdfResource predicate()

Description copied from interface: RdfTriple

Returns the predicate of the triple.

The predicate is an absolute IRI that specifies the property or relationship between the subject and the object of the triple.

Specified by:

predicate in interface RdfTriple

Returns:

a RdfResource representing the predicate of the triple; never null

object

public RdfTerm object()

Description copied from interface: RdfTriple

Returns the object of the triple.

The object can be:

• An absolute IRI or blank node identifier (RdfResource)
• A literal value (RdfLiteral)
• Another RdfTriple (RDF 1.2 - experimental support)

Specified by:

object in interface RdfTriple

Returns:

a RdfTerm representing the object of the triple; never null

toString

public java.lang.String toString()

Description copied from interface: RdfTerm

Returns a string representation of this RDF term.

Specified by:

toString in interface RdfTerm

Overrides:

toString in class java.lang.Object

Returns:

a string describing this RDF term.

hashCode

public int hashCode()

Description copied from interface: RdfTerm

Returns a hash code value for this RDF term.

Specified by:

hashCode in interface RdfTerm

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code consistent with RdfTerm.equals(Object).

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: RdfTerm

Compares this RDF term to the specified object. Implementations must override this method to provide equality checks appropriate to the term type.

Specified by:

equals in interface RdfTerm

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to compare with this term.

Returns:

true if the specified object is equal to this term; false otherwise.

printTriple

static final java.lang.StringBuilder printTriple(java.lang.StringBuilder builder,
                                                 RdfResource subject,
                                                 RdfResource predicate,
                                                 RdfTerm object)

printTripleTerm

static final java.lang.StringBuilder printTripleTerm(java.lang.StringBuilder builder,
                                                     RdfTriple triple)
