    • getDefaultRemoveGraphs

      public Set<IRI> 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

    • addDefaultRemoveGraph

      public void addDefaultRemoveGraph(IRI graphURI)
      Adds a graph URI to the set of default remove graph URIs.

    • removeDefaultRemoveGraph

      public boolean removeDefaultRemoveGraph(IRI graphURI)
      Removes a graph URI from the set of default remove graph URIs.
      Returns:
      true if the URI was removed from the set, false if the set did not contain the URI.

    • 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.
      Specified by:
      getDefaultInsertGraph in interface Dataset
      Returns:
      Returns the default insert graph.

    • setDefaultInsertGraph

      public void setDefaultInsertGraph(IRI defaultInsertGraph)
      Parameters:
      defaultInsertGraph - The default insert graph to used.

    • 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

    • addDefaultGraph

      public void addDefaultGraph(IRI graphURI)
      Adds a graph URI to the set of default graph URIs.

    • removeDefaultGraph

      public boolean removeDefaultGraph(IRI graphURI)
      Removes a graph URI from the set of default graph URIs.
      Returns:
      true if the URI was removed from the set, false if the set did not contain the URI.

    • getNamedGraphs

      public Set<IRI> getNamedGraphs()
      Gets the (unmodifiable) set of named graph URIs.
      Specified by:
      getNamedGraphs in interface Dataset

    • addNamedGraph

      public void addNamedGraph(IRI graphURI)
      Adds a graph URI to the set of named graph URIs.

    • removeNamedGraph

      public boolean removeNamedGraph(IRI graphURI)
      Removes a graph URI from the set of named graph URIs.
      Returns:
      true if the URI was removed from the set, false if the set did not contain the URI.

    • clear

      public void clear()
      Removes all graph URIs (both default and named) from this dataset.

      Overrides:
      toString in class Object
