# In order to view files created with our demo stream wrapper class,
# we need to use hook_file_download to grant any access. This route
# will make sure that we have an external URL for these files, and that
# our hook is called.
#
# In our implementation, access to the files is actually managed by
# permissions defined in file_example.permissions.yml. Since we also want our
# URLs to be served similar to how private: and temporary: URI are served by
# core, we also need to modify how the routing system handles the tail portion
# of the URL. Unlike Drupal 7, Drupal 8 does not ordinarily allow a "menu tail";
# URLs need to be of a definite length or the router will not process them. To
# get around this, we also implement a "path processor", which we define as a
# service in our services file. Our path processor will do the extra steps needed
# to process our session file URLs.

# In addition to the stream_wrapper_example.files route, which is actually matched by the router,
# we also need a route defintion to make our URLs.  This is never referenced by the
# routing system, but is used by our stream wrapper class to create external URLs.
