/**
|
|
* Class to provide access to ownCloud filesystem via a "view", and methods for
|
|
* working with files within that view (e.g. read, write, delete, etc.). Each
|
|
* view is restricted to a set of directories via a virtual root. The default view
|
|
* uses the currently logged in user's data directory as root (parts of
|
|
* OC_Filesystem are merely a wrapper for OC_FilesystemView).
|
|
*
|
|
* Apps that need to access files outside of the user data folders (to modify files
|
|
* belonging to a user other than the one currently logged in, for example) should
|
|
* use this class directly rather than using OC_Filesystem, or making use of PHP's
|
|
* built-in file manipulation functions. This will ensure all hooks and proxies
|
|
* are triggered correctly.
|
|
*
|
|
* Filesystem functions are not called directly; they are passed to the correct
|
|
* \OC\Files\Storage\Storage object
