It's a somewhat unusual pattern, spelling it out will help to move the vcs plugins setup closer to the now-usual pattern. Change-Id: Ie7b70e52d75e34cd36b6a1d55ca868e3edab44a7 Reviewed-by: Orgad Shaneh <orgads@gmail.com>

/* VcsManager:
|
|
* 1) Provides functionality for finding the IVersionControl * for a given
|
|
* filename (findVersionControlForDirectory). Note that the VcsManager assumes
|
|
* that if a IVersionControl * manages a directory, then it also manages
|
|
* all the files and all the subdirectories.
|
|
* It works by asking all IVersionControl * if they manage the file, and ask
|
|
* for the topmost directory it manages. This information is cached and
|
|
* VCSManager thus knows pretty fast which IVersionControl * is responsible.
|
|
* 2) Passes on the changes from the version controls caused by updating or
|
|
* branching repositories and routes them to its signals (repositoryChanged,
|
|
* filesChanged). */
