MetadataAbstractSubCommand

public MetadataAbstractSubCommand()

Method Detail

experimental

public boolean experimental()

Return true if the command is experimental or false otherwise.

Specified by:

experimental in interface Command<MetadataArgsDto extends IgniteDataTransferObject>

Returns:

true if the command is experimental or false otherwise.

printUsage

public final void printUsage(Logger log)

Print info for user about command (parameters, use cases and so on).

Specified by:

printUsage in interface Command<MetadataArgsDto extends IgniteDataTransferObject>

Parameters:

log - Logger to use.

parseArguments

public final void parseArguments(CommandArgIterator argIter)

Parse command-specific arguments.

Specified by:

parseArguments in interface Command<MetadataArgsDto extends IgniteDataTransferObject>

Parameters:

argIter - Argument iterator.

execute

public final Object execute(GridClientConfiguration clientCfg,
                            Logger log)
                     throws Exception

Actual command execution. Parameters for run should be already set by calling parseArguments method.

Specified by:

execute in interface Command<MetadataArgsDto extends IgniteDataTransferObject>

Parameters:

clientCfg - Thin client configuration if connection to cluster is necessary.
