Method Detail

parse

public OCommandExecutorSQLInsert parse(OCommandRequest iRequest)

Description copied from interface: OCommandExecutor

Parse the request. Once parsed the command can be executed multiple times by using the execute() method.

Specified by:

parse in interface OCommandExecutor

Parameters:

iRequest - Command request implementation.

Returns:

See Also:

#execute(Map...)

execute

public Object execute(Map<Object,Object> iArgs)

Execute the INSERT and return the ODocument object created.

Specified by:

execute in interface OCommandExecutor

Parameters:

iArgs - Optional variable arguments to pass to the command.

Returns:

See Also:

OCommandExecutor.parse(OCommandRequest)

getDistributedExecutionMode

public OCommandDistributedReplicateRequest.DISTRIBUTED_EXECUTION_MODE getDistributedExecutionMode()

Description copied from class: OCommandExecutorSQLAbstract

The command is replicated

Specified by:
