Method Detail

fallback

public static Dataset fallback(Dataset primary,
                               Dataset fallback)

getDefaultGraphs

public Set<URI> getDefaultGraphs()

Description copied from interface: Dataset

Gets the default graph URIs of this dataset. An empty default graph set and a non-empty named graph set indicates that the default graph is an empty graph. However, if both the default graph set and the named graph set are empty, that indicates that the store's default behaviour should be used.

Specified by:

getDefaultGraphs in interface Dataset

getNamedGraphs

public Set<URI> getNamedGraphs()

Description copied from interface: Dataset

Gets the named graph URIs of this dataset. An empty named graph set and a non-empty default graph set indicates that there are no named graphs. However, if both the default graph set and the named graph set are empty, that indicates that the store's default behaviour should be used.

Specified by:

getNamedGraphs in interface Dataset

getDefaultInsertGraph

public URI getDefaultInsertGraph()

Description copied from interface: Dataset

Gets the default insert graph URI of this dataset. An null value indicates that the store's default behaviour should be used, if not otherwise indicated in the operation.

Specified by:

getDefaultInsertGraph in interface Dataset

getDefaultRemoveGraphs

public Set<URI> getDefaultRemoveGraphs()

Description copied from interface: Dataset

Gets the default remove graph URIs of this dataset. An empty set indicates the the store's default behaviour should be used, if not otherwise indicated in the operation.

Specified by:

getDefaultRemoveGraphs in interface Dataset

toString

public String toString()
