Method Detail

containsGraph

public boolean containsGraph(Node graphNode)

Description copied from interface: DatasetGraph

Does the DatasetGraph contain a specific named graph? Whether a dataset contains a graph if there are no triples is not defined - see the specifc implementation. Some datasets are "open" - they have all graphs even if no triples and thsi returns true always.

Specified by:

containsGraph in interface DatasetGraph

Overrides:

containsGraph in class DatasetGraphWrapper

Returns:

boolean

getGraph

public Graph getGraph(Node graphNode)

Description copied from interface: DatasetGraph

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

Specified by:

getGraph in interface DatasetGraph

Overrides:

getGraph in class DatasetGraphReadOnly
