      • defaultGraph

        public RdfGraph defaultGraph()
        Description copied from interface: RdfDataset
        Returns the default graph of the dataset.

        The default graph is the unnamed graph in the dataset. It contains RDF triples that are not part of any named graph.

        Specified by:
        defaultGraph in interface RdfDataset
        Returns:
        the RdfGraph representing the default graph; never null

      • add

        public boolean add​(RdfQuad nquad)
        Description copied from interface: RdfQuadSet
        Adds RdfQuad to the RDF graph.

        This operation is unsupported by default and will throw an UnsupportedOperationException. Implementations that support modification of the set should override this method.

        Specified by:
        add in interface java.util.Collection<RdfQuad>
        Specified by:
        add in interface RdfQuadSet
        Specified by:
        add in interface java.util.Set<RdfQuad>
        Overrides:
        add in class java.util.HashSet<RdfQuad>
        Parameters:
        nquad - the RdfQuad to add
        Returns:
        true if the quad was successfully added (implementation dependent)

      • graphNames

        public java.util.Set<RdfResource> graphNames()
        Description copied from interface: RdfDataset
        Returns the set of graph names for all named graphs in the dataset.

        Each name is represented as a RdfResource, which can be an IRI or a blank node identifier.

        Specified by:
        graphNames in interface RdfDataset
        Returns:
        an immutable Set of RdfResource graph names; empty if no named graphs are present.

      • namedGraph

        public java.util.Optional<RdfGraph> namedGraph​(RdfResource graphName)
        Description copied from interface: RdfDataset
        Returns the named graph corresponding to the provided graph name.

        If the dataset does not contain a named graph with the specified name, an empty Optional is returned.

        Specified by:
        namedGraph in interface RdfDataset
        Parameters:
        graphName - the RdfResource identifying the named graph
        Returns:
        an Optional containing the RdfGraph if present; otherwise, Optional.empty()

      • contains

        public boolean contains​(RdfQuad quad)
        Description copied from interface: RdfQuadSet
        Checks if the set contains the specified RdfQuad.
        Specified by:
        contains in interface RdfQuadSet
        Parameters:
        quad - the RdfQuad to check
        Returns:
        true if the set contains the specified quad, false otherwise

      • stream

        public java.util.stream.Stream<RdfQuad> stream()
        Description copied from interface: RdfQuadSet
        Returns a Stream of the RDF quads in this set.

        The stream can be used for operations such as filtering or mapping over the quads.

        Specified by:
        stream in interface java.util.Collection<RdfQuad>
        Specified by:
        stream in interface RdfQuadSet
        Returns:
        a stream of RdfQuad objects in the set

      • iterator

        public java.util.Iterator<RdfQuad> iterator()
        Specified by:
        iterator in interface java.util.Collection<RdfQuad>
        Specified by:
        iterator in interface java.lang.Iterable<RdfQuad>
        Specified by:
        iterator in interface java.util.Set<RdfQuad>
        Overrides:
        iterator in class java.util.HashSet<RdfQuad>

      • remove

        public boolean remove​(RdfQuad quad)
        Description copied from interface: RdfQuadSet
        Removes RdfQuad from the RDF graph.

        This operation is unsupported by default and will throw an UnsupportedOperationException. Implementations that support removal of quads should override this method.

        Specified by:
        remove in interface RdfQuadSet
        Parameters:
        quad - the RdfQuad to remove
        Returns:
        true if the quad was successfully removed (implementation dependent)
