Inherited from Transport:

Method create_prefix Create all the directories leading down to self.base.
Method ensure_base Ensure that the directory this transport references exists.
Method get_segment_parameters Return the segment parameters for the top segment of the URL.
Method recommended_page_size Return the recommended page size for this transport.
Method relpath Return the local path portion from a given absolute path.
Method local_abspath Return the absolute path on the local filesystem.
Method has_multi Return True/False for each entry in relpaths
Method has_any Return True if any of the paths exist.
Method get_bytes Get a raw string of the bytes for a file at the given location.
Method get_smart_medium Return a smart client medium for this transport if possible.
Method readv Get parts of the file at the given relative path.
Method get_multi Get a list of file-like objects, one for each entry in relpaths.
Method put_bytes Atomically put the supplied bytes into the given location.
Method put_bytes_non_atomic Copy the string into the target location.
Method put_file_non_atomic Copy the file-like object into the target location.
Method mkdir_multi Create a group of directories
Method append_bytes Append bytes to a file at relpath.
Method append_multi Append the text in each file-like or string object to
Method copy Copy the item at rel_from to the location at rel_to.
Method copy_multi Copy a bunch of entries.
Method copy_to Copy a set of entries from self into another Transport.
Method copy_tree Copy a subtree from one relpath to another.
Method copy_tree_to_transport Copy a subtree from one transport to another.
Method move Move the item at rel_from to the location at rel_to.
Method move_multi Move a bunch of entries.
Method move_multi_to Move a bunch of entries to a single location.
Method delete_multi Queue up a bunch of deletes to be done.
Method delete_tree Delete an entire tree. This may require a listable transport.
Method __repr__ Undocumented
Method stat_multi Stat multiple files and return the information.
Method readlink Return a string representing the path to which the symbolic link points.
Method hardlink Create a hardlink pointing to source named link_name.
Method symlink Create a symlink pointing to source named link_name.
Method is_readonly Return true if this connection cannot be written to.
Method disconnect Undocumented
Method _translate_error Translate an IOError or OSError into an appropriate bzr error.
Method _pump Most children will need to copy from one file-like
Method _get_total Try to figure out how many entries are in multi,
Method _report_activity Notify that this transport has activity.
Method _update_pb Update the progress bar based on the current count
Method _iterate_over Iterate over all entries in multi, passing them to func,
Method _readv Get parts of the file at the given relative path.
Method _seek_and_read An implementation of readv that uses fp.seek and fp.read.
Method _sort_expand_and_combine Helper for readv.
Static Method _coalesce_offsets Yield coalesced offsets.
Method _can_roundtrip_unix_modebits Return true if this transport can store and retrieve unix modebits.
Method _reuse_for Undocumented
Method _redirected_to Returns a transport suitable to re-issue a redirected request.

NOTE: This only lists files, not subdirectories!

As with other listing functions, only some transports implement this,. you may check via listable() to determine if it will.
