public interface Dataset
Represents a dataset against which operations can be evaluated. A dataset consists of a default graph for read and
using operations, which is the RDF merge of one or more graphs, a
set of named graphs, and a single update graph for INSERT and DELETE. See
SPARQL Query Language for RDF for more info.

getDefaultInsertGraph
IRI getDefaultInsertGraph()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. -
getDefaultGraphs
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. -
getNamedGraphs
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.
