file selector
The $create()
factory method instantiates a FileSelector
given the 3 fields
described below.
base_dir
: The directory in which to select files. If the path exists but
doesn't point to a directory, this should be an error.
allow_not_found
: The behavior if base_dir
doesn't exist in the
filesystem. If FALSE
, an error is returned. If TRUE
, an empty
selection is returned
recursive
: Whether to recurse into subdirectories.
