normalize() public static method

Normalizes different types of "skip on empty" values including shortcuts to a callable:

  • null and false values are normalized to {@see \Yiisoft\Validator\EmptyCondition\NeverEmpty}.
  • true value is normalized to {@see \Yiisoft\Validator\EmptyCondition\WhenEmpty}.
  • A callable is left as is.
  • Other types are rejected causing the exception.

$skipOnEmpty boolean|callable|null

Raw "skip on empty" value of any type.
return callable

{
    if ($skipOnEmpty === false || $skipOnEmpty === null) {
        return new NeverEmpty();
    }
    if ($skipOnEmpty === true) {
        return new WhenEmpty();
    }
    return $skipOnEmpty;
