Method Details

getDefaultGraph

public Graph getDefaultGraph()

Description copied from interface: DatasetGraph

Get the default graph as a Jena Graph

Specified by:

getDefaultGraph in interface DatasetGraph

Overrides:

getDefaultGraph in class DatasetGraphWrapper

getUnionGraph

public Graph getUnionGraph()

Description copied from interface: DatasetGraph

Return a Graph that is the union of all named graphs in this dataset. This union graph is read-only (its prefix mapping in the current JVM may be changed but that may not persist).

Specified by:

getUnionGraph in interface DatasetGraph

Overrides:

getUnionGraph in class DatasetGraphWrapper

getGraph

public Graph getGraph(Node graphNode)

Description copied from interface: DatasetGraph

Get the graph named by graphNode : returns null when there is no such graph. NB Whether a dataset contains a graph if there are no triples is not defined - see the specific implementation. Some datasets are "open" - they have all graphs even if no triples.

Specified by:

getGraph in interface DatasetGraph

Overrides:

getGraph in class DatasetGraphWrapper

find

public Iterator<Quad> find(Quad quad)

Description copied from interface: DatasetGraph

Find matching quads in the dataset - may include wildcards, Node.ANY or null

Specified by:

find in interface DatasetGraph

Overrides:

find in class DatasetGraphWrapper

See Also:

• Graph.find(Triple)

find

public Iterator<Quad> find(Node g,
 Node s,
 Node p,
 Node o)

Description copied from interface: DatasetGraph

Find matching quads in the dataset (including default graph) - may include wildcards, Node.ANY or null

Specified by:

find in interface DatasetGraph

Overrides:

find in class DatasetGraphWrapper

See Also:

• Graph.find(Node,Node,Node)

findNG

public Iterator<Quad> findNG(Node g,
 Node s,
 Node p,
 Node o)

Description copied from interface: DatasetGraph

Find matching quads in the dataset in named graphs only - may include wildcards, Node.ANY or null

Specified by:

findNG in interface DatasetGraph

Overrides:

findNG in class DatasetGraphWrapper

See Also:

• Graph.find(Node,Node,Node)

contains

public boolean contains(Quad quad)

Description copied from interface: DatasetGraph

Test whether the dataset contains a quad (including default graph)- may include wildcards, Node.ANY or null

Specified by:

contains in interface DatasetGraph

Overrides:

contains in class DatasetGraphWrapper

contains

public boolean contains(Node g,
 Node s,
 Node p,
 Node o)

Description copied from interface: DatasetGraph

Test whether the dataset (including default graph) contains a quad - may include wildcards, Node.ANY or null

Specified by:

contains in interface DatasetGraph

Overrides:

contains in class DatasetGraphWrapper
