Detailed Description

A file object referring to either a standalone local file, or a file in a local repository with no database, for example an FileRepo repository.

Read-only.

Todo:
Currently it doesn't really work in the repository role, there are lots of functions missing. It is used by the WebStore extension in the standalone role.

Constructor & Destructor Documentation

◆ __construct()

UnregisteredLocalFile::__construct (   $title = false,
  $repo = false,
  $path = false,
  $mime = false 
)

Create an UnregisteredLocalFile based on a path or a (title,repo) pair.

A FileRepo object is not required here, unlike most other File classes.

Exceptions
MWException
Parameters
Title | bool$title
FileRepo | bool$repo
string | bool$path
string | bool$mime
