Constructor Details

DatasetGraphQuads

public DatasetGraphQuads()

Method Details

listGraphNodes

public Iterator<Node> listGraphNodes()

Description copied from interface: DatasetGraph

Iterate over all names of named graphs

removeGraph

public void removeGraph(Node graphName)

Description copied from interface: DatasetGraph

Remove all data associated with the named graph. This will include prefixes associated with the graph.

Specified by:

removeGraph in interface DatasetGraph

Specified by:

removeGraph in class DatasetGraphBase

addGraph

public void addGraph(Node graphName,
 Graph graph)

Description copied from interface: DatasetGraph

Add the given graph to the dataset. Replaces any existing data for the named graph; to add data, get the graph and add triples to it, or add quads to the dataset. Do not assume that the same Java object is returned by DatasetGraph.getGraph(org.apache.jena.graph.Node)

Specified by:

addGraph in interface DatasetGraph

Specified by:

addGraph in class DatasetGraphBase

find

public abstract 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

See Also:

• Graph.find(Node,Node,Node)

findNG

public abstract 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

See Also:

• Graph.find(Node,Node,Node)

add

public abstract void add(Quad quad)

Description copied from interface: DatasetGraph

Add a quad

Specified by:

add in interface DatasetGraph

Overrides:

add in class DatasetGraphBase

delete

public abstract void delete(Quad quad)

Description copied from interface: DatasetGraph

Delete a quad

Specified by:

delete in interface DatasetGraph

Overrides:

delete in class DatasetGraphBase
