Method Detail

clear

public void clear()

Description copied from interface: GraphLike

Remove all statements.

Specified by:

clear in interface Graph

Specified by:

clear in interface GraphLike<Triple>

Overrides:

clear in class AbstractJsonLdGraphLike<Triple>

add

public void add(Triple t)

Description copied from interface: GraphLike

Add a statement.

Specified by:

add in interface Graph

Specified by:

add in interface GraphLike<Triple>

Overrides:

add in class AbstractJsonLdGraphLike<Triple>

Parameters:

t - The TripleLike statement to add

add

public void add(BlankNodeOrIRI subject,
                IRI predicate,
                RDFTerm object)

Description copied from interface: Graph

Adds a triple to the graph, possibly mapping any of the components to those supported by this Graph.

Specified by:

add in interface Graph

Parameters:

subject - The triple subject

predicate - The triple predicate

object - The triple object

contains

public boolean contains(BlankNodeOrIRI subject,
                        IRI predicate,
                        RDFTerm object)

Description copied from interface: Graph

Checks if graph contains a pattern of triples.

Specified by:

contains in interface Graph

Parameters:

subject - The triple subject (null is a wildcard)

predicate - The triple predicate (null is a wildcard)

object - The triple object (null is a wildcard)

Returns:

True if the Graph contains any Triples that match the given pattern.

contains

public boolean contains(Triple t)

Description copied from interface: GraphLike

Check if statement is contained.

Specified by:

contains in interface Graph

Specified by:

contains in interface GraphLike<Triple>

Overrides:

contains in class AbstractJsonLdGraphLike<Triple>

Parameters:

t - The TripleLike statement to check

Returns:

True if the statement is contained

remove

public void remove(BlankNodeOrIRI subject,
                   IRI predicate,
                   RDFTerm object)

Description copied from interface: Graph

Removes a concrete pattern of triples from the graph.

Specified by:

remove in interface Graph

Parameters:

subject - The triple subject (null is a wildcard)

predicate - The triple predicate (null is a wildcard)

object - The triple object (null is a wildcard)

remove

public void remove(Triple t)

Description copied from interface: GraphLike

Add a statement.

Specified by:

remove in interface Graph

Specified by:

remove in interface GraphLike<Triple>

Parameters:

t - The TripleLike statement to add

size

public long size()

Description copied from interface: GraphLike

Number of statements.

Specified by:

size in interface Graph

Specified by:

size in interface GraphLike<Triple>

Returns:

Number of statements

stream

public java.util.stream.Stream<JsonLdTriple> stream(BlankNodeOrIRI subject,
                                                    IRI predicate,
                                                    RDFTerm object)

Description copied from interface: Graph

Gets all triples contained by the graph matched with the pattern.

The iteration does not contain any duplicate triples, as determined by the Triple.equals(Object) method for each Triple.

The behaviour of the Stream is not specified if Graph.add(Triple), Graph.remove(Triple) or Graph.clear() are called on the Graph before it terminates.

Implementations may throw ConcurrentModificationException from Stream methods if they detect a conflict while the Stream is active.

Specified by:

stream in interface Graph

Parameters:

subject - The triple subject (null is a wildcard)

predicate - The triple predicate (null is a wildcard)

object - The triple object (null is a wildcard)

Returns:

A Stream over the matched triples.

asTripleOrQuad

JsonLdTriple asTripleOrQuad(com.github.jsonldjava.core.RDFDataset.Quad jsonldQuad)

Description copied from class: AbstractJsonLdGraphLike

Convert JsonLd Quad to a Commons RDF Triple or Quad

Specified by:

asTripleOrQuad in class AbstractJsonLdGraphLike<Triple>

Parameters:

jsonldQuad - jsonld quad to convert

Returns:

converted TripleLike
