Methods

__construct

public __construct(string $name = null, callable $directoryIteratorProvider = null, callable $isReadableProvider = null): mixed

Parameters:

Parameter	Type	Description
$name	string	The name of the command; passing null means it must be set in configure()
$directoryIteratorProvider	callable
$isReadableProvider	callable

---

configure

Configures the current command.

protected configure(): mixed

---

execute

Executes the current command.

protected execute(\Symfony\Component\Console\Input\InputInterface $input, \Symfony\Component\Console\Output\OutputInterface $output): int

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.

$output	\Symfony\Component\Console\Output\OutputInterface

Return Value:

0 if everything went fine, or an exit code
