TYPO3 main API: ResourceStorage

ResourceStorage implements ResourceStorageInterface

A "mount point" inside the TYPO3 file handling.

A "storage" object handles

abstraction to the driver
permissions (from the driver, and from the user, + capabilities)
an entry point for files, folders, and for most other operations

== Driver entry point The driver itself, that does the actual work on the file system, is inside the storage but completely shadowed by the storage, as the storage also handles the abstraction to the driver

The storage can be on the local system, but can also be on a remote system. The combination of driver + configurable capabilities (storage is read-only e.g.) allows for flexible uses.

== Permission system As all requests have to run through the storage, the storage knows about the permissions of a BE/FE user, the file permissions / limitations of the driver and has some configurable capabilities. Additionally, a BE user can use "filemounts" (known from previous installations) to limit his/her work-zone to only a subset (identifier and its subfolders/subfolders) of the user itself.

Check 1: "User Permissions" [is the user allowed to write a file) [is the user allowed to write a file] Check 2: "File Mounts" of the User (act as subsets / filters to the identifiers) [is the user allowed to do something in this folder?] Check 3: "Capabilities" of Storage (then: of Driver) [is the storage/driver writable?] Check 4: "File permissions" of the Driver [is the folder writable?]
