public NodeTupleTableConcrete(int N,
 TupleIndex[] indexes,
 NodeTable nodeTable,
 DatasetControl dsControl)

Method Details

getPolicy

public DatasetControl getPolicy()

Description copied from interface: NodeTupleTable

Return the current policy, if any, for this NodeTupleTable

Specified by:

getPolicy in interface NodeTupleTable

addRow

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

Specified by:

addRow in interface NodeTupleTable

deleteRow

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

Specified by:

deleteRow in interface NodeTupleTable

getTupleLen

public int getTupleLen()

Description copied from interface: NodeTupleTable

The length of tuples managed. -1 indicates "variable length"

Specified by:

find

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

Find by node.

Specified by:

find in interface NodeTupleTable

findAsNodeIds

public 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" (when a node is known to be unknown) for not found as well as NullIterator (when no tuples are found (unknown unknown).

Specified by:

findAsNodeIds in interface NodeTupleTable

find

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

Description copied from interface: NodeTupleTable

Find all tuples

Specified by:

findAll in interface NodeTupleTable

getTupleTable

public final TupleTable getTupleTable()

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

Specified by:

getTupleTable in interface NodeTupleTable

getNodeTable

public final NodeTable getNodeTable()

Return the node table

Specified by:

getNodeTable in interface NodeTupleTable
