LocalStream

Defines a Drupal stream wrapper base class for local files.

This class provides a complete stream wrapper implementation. URIs such as "public://example.txt" are expanded to a normal filesystem path such as "sites/default/files/example.txt" and then PHP filesystem functions are invoked.

Drupal\Core\StreamWrapper\LocalStream implementations need to implement at least the getDirectoryPath() and getExternalUrl() methods.
