Constructor Details

GraphTDB

public GraphTDB(org.apache.jena.sparql.core.DatasetGraph dataset,
 org.apache.jena.graph.Node graphName)

Method Details

getDatasetGraphTDB

public abstract DatasetGraphTDB getDatasetGraphTDB()

Return the associated DatasetGraphTDB. For non-transactional, that's the base storage. For transactional, it is the current transaction wrapper DatasetGraphTDB.

Immediate validity only. Not valid across transaction boundaries, nor non-transactional to transactional.

getDatasetGraphTransaction

public abstract DatasetGraphTransaction getDatasetGraphTransaction()

Return the DatasetGraphTransaction. If this wrapping a base DatasetGraphTDB, return null.

getNodeTupleTable

public NodeTupleTable getNodeTupleTable()

The NodeTupleTable for this graph - valid only inside the transaction or non-transactional.

sync

public final void sync()

Specified by:

sync in interface org.apache.jena.atlas.lib.Sync

Overrides:

sync in class org.apache.jena.sparql.core.GraphView

close

public final void close()

Specified by:

close in interface org.apache.jena.atlas.lib.Closeable

Specified by:

close in interface org.apache.jena.graph.Graph

Overrides:

close in class org.apache.jena.graph.impl.GraphBase

remove

public void remove(org.apache.jena.graph.Node s,
 org.apache.jena.graph.Node p,
 org.apache.jena.graph.Node o)

Specified by:

remove in interface org.apache.jena.graph.Graph

Overrides:

remove in class org.apache.jena.sparql.core.GraphView
