    • getDefaultGraphs

      public Set<IRI> 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<IRI> 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.

    • getDefaultInsertGraph

      public IRI 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.

    • getDefaultRemoveGraphs

      public Set<IRI> getDefaultRemoveGraphs()
      Description copied from interface: Dataset
