Method Detail

getGraph

public static OrientGraph getGraph(boolean autoStartTx,
                                   OModifiableBoolean shouldBeShutDown)

Returns a Transactional OrientGraph implementation from the current database in thread local.

Parameters:

autoStartTx - Whether returned graph will start transaction before each operation till commit automatically or user should do it explicitly be calling OrientBaseGraph.getRawGraph() method ODatabaseDocumentTx.begin().

Returns:

Transactional OrientGraph implementation from the current database in thread local.

getGraphNoTx

public static OrientGraphNoTx getGraphNoTx(OModifiableBoolean shouldBeShutDown)

Returns:

a Non Transactional OrientGraph implementation from the current database in thread local.

getAnyGraph

public static OrientBaseGraph getAnyGraph(OModifiableBoolean shouldBeShutDown)

Returns:

any graph if available, otherwise a Non Transactional OrientGraph implementation from the current database in thread local.

runInTx

public static <T> T runInTx(OrientGraph graph,
                            OGraphCommandExecutorSQLFactory.GraphCallBack<T> callBack)

runInTx

public static <T> T runInTx(OGraphCommandExecutorSQLFactory.GraphCallBack<T> callBack)

runWithAnyGraph

public static <T> T runWithAnyGraph(OGraphCommandExecutorSQLFactory.GraphCallBack<T> callBack)

getDatabase

public static ODatabaseDocument getDatabase()

getCommandNames

public Set<String> getCommandNames()

Specified by:

getCommandNames in interface OCommandExecutorSQLFactory

Returns:

Set of supported command names of this factory

public OCommandExecutorSQLAbstract createCommand(String name)
                                          throws OCommandExecutionException

Create command for the given name. returned command may be a new instance each time or a constant.

Specified by:

createCommand in interface OCommandExecutorSQLFactory

Returns:

OCommandExecutorSQLAbstract : created command

Throws:

OCommandExecutionException - : when command creation fail
