ModuleHandler::alter in core/lib/Drupal/Core/Extension/ModuleHandler.php

File

core/lib/Drupal/Core/Extension/ModuleHandler.php, line 475

Class

ModuleHandler

Class that manages modules in a Drupal installation.

Namespace

Drupal\Core\Extension

Code

protected function reOrderModulesForAlter(array $modules, string $hook) : array {
    // Order by module order first.
    $modules = array_intersect(array_keys($this->moduleList), $modules);
    // Alter expects the module list to be in the keys.
    $implementations = array_fill_keys($modules, FALSE);
    // Let modules adjust the order solely based on the primary hook. This
    // ensures the same module order regardless of whether this block
    // runs. Calling $this->alter() recursively in this way does not
    // result in an infinite loop, because this call is for a single
    // $type, so we won't end up in this method again.
    $this->alter('module_implements', $implementations, $hook);
    return array_keys($implementations);
}
