Class

StreamWrapperManager
Provides a StreamWrapper manager.

Namespace

Drupal\Core\StreamWrapper

Code

public function unregister() {
    // Normally, there are definitely wrappers set for the ALL filter. However,
    // in some cases involving many container rebuilds (e.g. BrowserTestBase),
    // $this->wrappers may be empty although wrappers are still registered
    // globally. Thus an isset() check is needed before iterating.
    if (isset($this->wrappers[StreamWrapperInterface::ALL])) {
        foreach (array_keys($this->wrappers[StreamWrapperInterface::ALL]) as $scheme) {
            stream_wrapper_unregister($scheme);
        }
    }
}
