FsObjReadOnly
Implemented in:
FsObjReadOnly is an implementation of the FsObj interface. It is a proxy object that wraps another FsObj object and allows only read access to it.
Note that the method file_socket_connect() is not forwarded by FsObjReadOnly. Connecting to a socket is deemed to be read/write access since it often provides a way to make changes, even though it does not itself involve changing the filesystem tree.
