public interface Dataset

  • Method Details

    • getDefaultRemoveGraphs

      Set<IRI> getDefaultRemoveGraphs()
      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.
    • 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

      Set<IRI> 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

      Set<IRI> 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.
