OCommandExecutorScript

public OCommandExecutorScript()

Method Details

parse

public OCommandExecutorScript 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:

Description copied from interface: OCommandDistributedReplicateRequest

Returns the execution mode when distributed configuration is active:

• LOCAL: executed on local node only
• REPLICATE: executed on all the nodes and expect the same result
• SHARDED: executed on all the involved nodes and merge results

Specified by:

getDistributedExecutionMode in interface OCommandDistributedReplicateRequest

execute

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

Description copied from interface: OCommandExecutor

Execute the requested command parsed previously.

Specified by:
