Method Detail

create

public static DatasetGraph create()

add

public void add(Quad quad)

Description copied from interface: DatasetGraph

Add a quad

Specified by:

add in interface DatasetGraph

Overrides:

add in class DatasetGraphNull

delete

public void delete(Quad quad)

Description copied from interface: DatasetGraph

Delete a quad

Specified by:

delete in interface DatasetGraph

Overrides:

delete in class DatasetGraphNull

deleteAny

public void deleteAny(Node g,
                      Node s,
                      Node p,
                      Node o)

Description copied from interface: DatasetGraph

Delete any quads matching the pattern

Specified by:

deleteAny in interface DatasetGraph

Overrides:

deleteAny in class DatasetGraphNull

setDefaultGraph

public void setDefaultGraph(Graph g)

Description copied from interface: DatasetGraph

Set the default graph. Set the active graph if it was null. This replaces the contents default graph, not merge data into it. Do not assume that the same object is returned by DatasetGraph.getDefaultGraph()

Specified by:

setDefaultGraph in interface DatasetGraph

Overrides:

setDefaultGraph in class DatasetGraphNull

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

Overrides:

addGraph in class DatasetGraphNull

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

Overrides:

removeGraph in class DatasetGraphNull

prefixes

public PrefixMap prefixes()

Description copied from interface: DatasetGraph

Prefixes for this DatasetGraph
