Class

Provides module updates versions handling.

Namespace

Drupal\Core\Update

Code

public function getAvailableUpdates(string $module) : array {

        // hook_update_N() functions end this way, and there are other
        // possible functions which match '_update_'. We use preg_grep() here
        // since looping through all PHP functions can take significant page
        // execution time and this function is called on every administrative page
        // via system_requirements().
