Method Detail

setExecutionLogging

@Deprecated
public static void setExecutionLogging(boolean state)

Deprecated. Use setExecutionLogging(Explain.InfoLevel)}

Set or unset execution logging - logging is to logger "com.hp.hpl.jena.tdb.exec" at level INFO. An appropriate logging configuration is also required.

setExecutionLogging

public static void setExecutionLogging(com.hp.hpl.jena.tdb.solver.Explain.InfoLevel infoLevel)

Set execution logging - logging is to logger "com.hp.hpl.jena.tdb.exec" at level INFO. An appropriate logging configuration is also required.

getContext

public static com.hp.hpl.jena.sparql.util.Context getContext()

init

public static void init()

TDB System initialization - normally, this is not explicitly called because all routes to use TDB will cause initialization to occur. However, calling it repeatedly is safe and low cost.

closedown

public static void closedown()

Release any and all system resources held by TDB. This does NOT close or release datasets or graphs held by client code.

setOptimizerWarningFlag

public static void setOptimizerWarningFlag(boolean b)

Set the global flag that control the "No BGP optimizer" warning. Set to false to silence the warning

sync

public static void sync(com.hp.hpl.jena.rdf.model.Model model)

Sync a TDB-backed Model. Do nothing if not TDB-backed.

sync

public static void sync(com.hp.hpl.jena.graph.Graph graph)

Sync a TDB-backed Graph. Do nothing if not TDB-backed.

sync

public static void sync(com.hp.hpl.jena.query.Dataset dataset)

Sync a TDB-backed Dataset. Do nothing if not TDB-backed.

sync

public static void sync(com.hp.hpl.jena.sparql.core.DatasetGraph dataset)

Sync a TDB-backed DatasetGraph. Do nothing if not TDB-backed.
