2. 10 core/lib/Drupal/Component/Assertion/Inspector.php \Drupal\Component\Assertion\Inspector::assertAll()

Asserts callback returns TRUE for each member of a traversable.

This is less memory intensive than using array_filter() to build a second array and then comparing the arrays. Many of the other functions in this collection alias this function passing a specific callback to make the code more readable.

Parameters

callable $callable: Callback function.

mixed $traversable: Variable to be examined.

Return value

bool TRUE if $traversable can be traversed and $callable returns TRUE on all members.
