Method Detail

newInstance

public static RdfTripleConsumer newInstance(com.apicatalog.rdf.api.RdfQuadConsumer consumer)

defaultGraph

public RdfTripleConsumer defaultGraph()

Description copied from interface: RdfTripleConsumer

Sets the default graph as the active scope. This method is invoked when triples belong to the unnamed default graph.

Specified by:

defaultGraph in interface RdfTripleConsumer

Returns:

An instance enabling fluent programming; never null.

namedGraph

public RdfTripleConsumer namedGraph(java.lang.String graph)

Description copied from interface: RdfTripleConsumer

Sets a named graph as the active scope. Ensures that subsequent triples are associated with the specified graph.

Specified by:

namedGraph in interface RdfTripleConsumer

Parameters:

graph - The name of the graph (IRI or blank node identifier prefixed with "_:"); never null.

Returns:

An instance enabling fluent programming; never null.

triple

public RdfTripleConsumer triple(java.lang.String subject,
                                java.lang.String predicate,
                                java.lang.String object)
                         throws com.apicatalog.rdf.api.RdfConsumerException

Description copied from interface: RdfTripleConsumer

Accepts an RDF triple where the object is an IRI or a blank node. The triple is processed within the currently active graph scope.

Specified by:

triple in interface RdfTripleConsumer

Parameters:

subject - The subject of the triple (IRI or blank node identifier prefixed with "_:"); never null.

predicate - The predicate of the triple (IRI); never null.

object - The object of the triple (IRI or blank node identifier prefixed with "_:"); never null.

Returns:

An instance enabling fluent programming; never null.

Throws:

com.apicatalog.rdf.api.RdfConsumerException - if an error occurs while processing the N-Quad statement

triple

public RdfTripleConsumer triple(java.lang.String subject,
                                java.lang.String predicate,
                                java.lang.String literal,
                                java.lang.String datatype)
                         throws com.apicatalog.rdf.api.RdfConsumerException

Description copied from interface: RdfTripleConsumer

Accepts an RDF triple where the object is a literal with a datatype. Optimized for efficient handling of typed literals. The triple is processed within the currently active graph scope.

Specified by:

triple in interface RdfTripleConsumer

Parameters:

subject - The subject of the triple (IRI or blank node identifier prefixed with "_:"); never null.

predicate - The predicate of the triple (IRI); never null.

literal - The literal value of the object; never null.

datatype - The datatype IRI of the literal; never null.

Returns:

An instance enabling fluent programming; never null.

Throws:

com.apicatalog.rdf.api.RdfConsumerException - if an error occurs while processing the N-Quad statement

triple

public RdfTripleConsumer triple(java.lang.String subject,
                                java.lang.String predicate,
                                java.lang.String literal,
                                java.lang.String language,
                                java.lang.String direction)
                         throws com.apicatalog.rdf.api.RdfConsumerException

Description copied from interface: RdfTripleConsumer

Accepts an RDF triple where the object is a localized string value. Optimized for efficient handling of language-tagged literals. The triple is processed within the currently active graph scope.

Specified by:

triple in interface RdfTripleConsumer

Parameters:

subject - The subject of the triple (IRI or blank node identifier prefixed with "_:"); never null.

predicate - The predicate of the triple (IRI); never null.

literal - The literal value of the object; never null.

language - The language tag of the literal; never null.

direction - The text direction of the literal (optional, may be null).

Returns:

An instance enabling fluent programming; never null.

Throws:

com.apicatalog.rdf.api.RdfConsumerException - if an error occurs while processing the N-Quad statement
