__construct() public method

public mixed __construct ( callable|null $callback = null, string|null $method = null, boolean|callable|null $skipOnEmpty = null, boolean $skipOnError = false, Closure|null $when = null )
$callback callable|null

Callable with the function ($value, $rule, $context): Result signature that performs the validation. Mutually exclusive with {@see $method}.
$method string|null

Name of a validated object method with the function ($value, $rule, $context): Result signature that performs the validation. Mutually exclusive with {@see $callback}.
$skipOnEmpty boolean|callable|null

Whether to skip this rule if the value validated is empty. See {@see \Yiisoft\Validator\SkipOnEmptyInterface}.
$skipOnError boolean

Whether to skip this rule if any of the previous rules gave an error. See {@see \Yiisoft\Validator\SkipOnErrorInterface}.
$when Closure|null

A callable to define a condition for applying the rule. See {@see \Yiisoft\Validator\WhenInterface}.
throws InvalidArgumentException

When neither {@see $callback} nor {@see $method} is specified or both are specified at the same time.
