Set a hook implementation to fire before others.

This method tries to keep existing order as much as possible. For example, if there are five hook implementations, A, B, C, D, E firing in this order then moving D before B will set it after A.

Parameters

\Drupal\Core\DependencyInjection\ContainerBuilder $container: The container builder.

string $hook: The name of the hook.

string $class_and_method: Class and method separated by :: containing the hook implementation which should be changed.

string ...$others: A list specifying the other implementations this hook should fire before. Every list member is a class and method separated by ::.

Return value

void
