Method Details

__construct() public method

$usage	string	The usage, it'll be prefixed with the command name
return	Command	The current instance

configure() protected method

Configures the current command.

protected configure ( )

execute() protected method

This method is not abstract because you can use this class as a concrete class. In this case, instead of defining the execute() method, you set the code to execute by passing a Closure to the setCode() method.

getAliases() public method

Returns the aliases for the command.

public getAliases ( ) : array
return	array	An array of aliases for the command

getApplication() public method

Gets the application instance for this command.

public getApplication ( ) : Application

getDefinition() public method

Gets the InputDefinition attached to this Command.

public getDefinition ( ) : Symfony\Component\Console\Input\InputDefinition
return	Symfony\Component\Console\Input\InputDefinition	An InputDefinition instance

getDescription() public method

Returns the description for the command.

public getDescription ( ) : string
return	string	The description for the command

getHelp() public method

Returns the help for the command.

public getHelp ( ) : string
return	string	The help for the command

getHelper() public method

Gets a helper instance by name.

public getHelper ( string $name ) : mixed
$name	string	The helper name
return	mixed	The helper value

getHelperSet() public method

Gets the helper set.

public getHelperSet ( ) : Symfony\Component\Console\Helper\HelperSet
return	Symfony\Component\Console\Helper\HelperSet	A HelperSet instance

getName() public method

Returns the command name.

public getName ( ) : string
return	string	The command name

getNativeDefinition() public method

Can be overridden to provide the original command representation when it would otherwise be changed by merging with the application InputDefinition. This method is not part of public API and should not be used directly.

public getNativeDefinition ( ) : Symfony\Component\Console\Input\InputDefinition
return	Symfony\Component\Console\Input\InputDefinition	An InputDefinition instance

getProcessedHelp() public method

Returns the processed help for the command replacing the %command.name% and %command.full_name% patterns with the real values dynamically.

public getProcessedHelp ( ) : string
return	string	The processed help for the command

getSynopsis() public method

Returns the synopsis for the command.

public getSynopsis ( boolean $short = false ) : string
$short	boolean	Whether to show the short version of the synopsis (with options folded) or not
return	string	The synopsis

getUsages() public method

Returns alternative usages of the command.

public getUsages ( ) : array
return	array

ignoreValidationErrors() public method

This is mainly useful for the help command.

public ignoreValidationErrors ( )

initialize() protected method

This is mainly useful when a lot of commands extends one main command where some things need to be initialized based on the input arguments and options.

protected initialize ( Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output )
$input	Symfony\Component\Console\Input\InputInterface	An InputInterface instance
$output	Symfony\Component\Console\Output\OutputInterface	An OutputInterface instance

interact() protected method

This method is executed before the InputDefinition is validated. This means that this is the only place where the command can interactively ask for values of missing required arguments.

protected interact ( Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output )
$input	Symfony\Component\Console\Input\InputInterface	An InputInterface instance
$output	Symfony\Component\Console\Output\OutputInterface	An OutputInterface instance

isEnabled() public method

Override this to check for x or y and return false if the command can not run properly under the current conditions.

public isEnabled ( ) : boolean
return	boolean

isHidden() public method

public isHidden ( ) : boolean
return	boolean	Whether the command should be publicly shown or not.

mergeApplicationDefinition() public method

This method is not part of public API and should not be used directly.
