  • Method Details

    • addRow

      boolean addRow(org.apache.jena.graph.Node... nodes)

    • deleteRow

      boolean deleteRow(org.apache.jena.graph.Node... nodes)

    • getTupleLen

      int getTupleLen()
      The length of tuples managed. -1 indicates "variable length"

    • find

      Iterator<org.apache.jena.atlas.lib.tuple.Tuple<org.apache.jena.graph.Node>> find(org.apache.jena.graph.Node... nodes)
      Find by node.

    • findAsNodeIds

      Iterator<org.apache.jena.atlas.lib.tuple.Tuple<NodeId>> findAsNodeIds(org.apache.jena.graph.Node... nodes)
      Find by node - return an iterator of NodeIds. Can return "null" for not found as well as NullIterator

    • find

      Iterator<org.apache.jena.atlas.lib.tuple.Tuple<NodeId>> find(NodeId... ids)
      Find by NodeId.

    • find

      Iterator<org.apache.jena.atlas.lib.tuple.Tuple<NodeId>> find(org.apache.jena.atlas.lib.tuple.Tuple<NodeId> ids)
      Find by NodeId.

    • findAll

      Iterator<org.apache.jena.atlas.lib.tuple.Tuple<NodeId>> findAll()
      Find all tuples

    • getTupleTable

      TupleTable getTupleTable()
      Return the underlying tuple table - used with great care by tools that directly manipulate internal structures.

    • getNodeTable

      NodeTable getNodeTable()
      Return the node table

    • isEmpty

      boolean isEmpty()

    • clear

      void clear()
      Clear the tuple table. After this operation, find* will find nothing. This does not mean all data has been removed - for example, it does not mean that any node table has been emptied.

    • size

      long size()

    • getPolicy

      DatasetControl getPolicy()
      Return the current policy, if any, for this NodeTupleTable
