Method Details

parse

public OCommandExecutorSQLUpdate 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<Object, Object>...)

execute

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

Description copied from interface: OCommandExecutor

Execute the requested command parsed previously.

Specified by:

execute in interface OCommandExecutor

Parameters:

iArgs - Optional variable arguments to pass to the command.

Returns:

See Also:

result

public boolean result(Object iRecord)

Update current record.

Specified by:

result in interface OCommandResultListener

Parameters:

iRecord - Current record

Returns:

True to continue the query, otherwise false

getSyntax

public String getSyntax()

Specified by:

getSyntax in interface OCommandExecutor

Overrides:

getSyntax in class OBaseParser

getDistributedExecutionMode

public OCommandDistributedReplicateRequest.DISTRIBUTED_EXECUTION_MODE getDistributedExecutionMode()

Description copied from class: OCommandExecutorSQLAbstract

The command is replicated

Specified by:

getDistributedExecutionMode in interface OCommandDistributedReplicateRequest

Overrides:

getDistributedExecutionMode in class OCommandExecutorSQLAbstract

getDistributedResultManagement

public OCommandDistributedReplicateRequest.DISTRIBUTED_RESULT_MGMT getDistributedResultManagement()

Description copied from interface: OCommandDistributedReplicateRequest

Returns how to manage the distributed result between:

• CHECK_FOR_EQUALS: all results must be the same
• MERGE: merges results. This is typically used on sharding

Specified by:

getDistributedResultManagement in interface OCommandDistributedReplicateRequest

Overrides:

getDistributedResultManagement in class OCommandExecutorAbstract

end

public void end()

Description copied from interface: OCommandResultListener

Called at the end of processing. This is useful to clean-up local attributes.

Specified by:

end in interface OCommandResultListener

getSecurityOperationType

public int getSecurityOperationType()

Description copied from interface: OCommandExecutor

Returns the security operation type use to check about security.

Specified by:

getSecurityOperationType in interface OCommandExecutor

Overrides:

getSecurityOperationType in class OCommandExecutorAbstract

Returns:

See Also:

parseMerge

protected void parseMerge()

getBlock

protected String getBlock(String fieldValue)

parseReturn

protected void parseReturn()
                    throws OCommandSQLParsingException

Parses the returning keyword if found.

Throws:

OCommandSQLParsingException

getQuorumType

public OCommandDistributedReplicateRequest.QUORUM_TYPE getQuorumType()

Description copied from interface: OCommandDistributedReplicateRequest

Returns the quorum type for the command:

• NONE: no quorum
• READ: configured Read quorum
• WRITE: configured Write quorum
• ALL: all nodes

Specified by:

getQuorumType in interface OCommandDistributedReplicateRequest

getResult

public Object getResult()

Specified by:

getResult in interface OCommandResultListener
