Interface Dataset

All Known Implementing Classes:
Datasets.DatasetImpl
public interface Dataset

Amalgum of an RDF 1.1 Dataset, a SPARQL 1.1 RDF Dataset & a SPARQL 1.1 update [graph](https://www.w3.org/TR/sparql11-update/#deleteInsert)

Both RDF 1.1 and SPARQL specify that there is a single default graph per Dataset. However, with SPARQL 1.1 you can specify multiple graphs and the single default graph is presumed to be the RDF merge of the specified graphs

This Dataset representation takes the RDF 1.1 position wrt to graph names; both bnodes and IRIs are legal identifiers.

  • Method Details

    • isEmpty

      default boolean isEmpty()

    • defaultRemoveGraphs

      @Nonnull com.google.common.collect.ImmutableSet<Resource> defaultRemoveGraphs()
      The set of graphs write queries can remove data from.
      Returns:
      the graphs

    • defaultInsertGraph

      @Nonnull Optional<Resource> defaultInsertGraph()
      Optionally, the graph where write queries should insert data.
      Returns:
      the graph to insert into

    • defaultGraphs

      @Nonnull com.google.common.collect.ImmutableSet<Resource> defaultGraphs()
      The set of graphs, the union of which, makes up the default component of the active graph
      Returns:
      the default graphs; when empty, the default graph of the database is used

    • namedGraphs

      @Nonnull com.google.common.collect.ImmutableSet<Resource> namedGraphs()
      The set of named graphs that are a part of the active graph of the dataset.
      Returns:
      the named graphs

    • excludedGraphs

      @Nonnull com.google.common.collect.ImmutableSet<Resource> excludedGraphs()
      The set of graphs to be excluded from the query dataset. Returns the set of graphs, possibly including wildcards, excluded from both the default and named scope of the dataset.
