Detailed Description

Class to represent a local file in the wiki's own database.

Provides methods to retrieve paths (physical, logical, URL), to generate image thumbnails or for uploading.

Note that only the repo object knows what its file class is called. You should never name a file class explictly outside of the repo class. Instead use the repo's factory functions to generate file objects, for example:

RepoGroup::singleton()->getLocalRepo()->newFile( $title );

Consider the services container below;

$services = MediaWikiServices::getInstance();

The convenience services $services->getRepoGroup()->getLocalRepo()->newFile() and $services->getRepoGroup()->findFile() should be sufficient in most cases.

@TODO: DI - Instead of using MediaWikiServices::getInstance(), a service should ideally accept a RepoGroup in its constructor and then, use $this->repoGroup->findFile() and $this->repoGroup->getLocalRepo()->newFile().
