44 * @short_description: an object representing a File Transfer
45 * @include: libempathy/empathy-ft-handler
47 * #EmpathyFTHandler is the object which represents a File Transfer with all
49 * The creation of an #EmpathyFTHandler is done with
50 * empathy_ft_handler_new_outgoing() or empathy_ft_handler_new_incoming(),
51 * even though clients should not need to call them directly, as
52 * #EmpathyFTFactory does it for them. Remember that for the file transfer
53 * to work with an incoming handler,
54 * empathy_ft_handler_incoming_set_destination() should be called after
55 * empathy_ft_handler_new_incoming(). #EmpathyFTFactory does this
57 * It's important to note that, as the creation of the handlers is async, once
58 * an handler is created, it already has all the interesting properties set,
59 * like filename, total bytes, content type and so on, making it useful
60 * to be displayed in an UI.
61 * The transfer API works like a state machine; it has three signals,
62 * ::transfer-started, ::transfer-progress, ::transfer-done, which will be
63 * emitted in the relevant phases.
64 * In addition, if the handler is created with checksumming enabled,
65 * other three signals (::hashing-started, ::hashing-progress, ::hashing-done)
66 * will be emitted before or after the transfer, depending on the direction
67 * (respectively outgoing and incoming) of the handler.
68 * At any time between the call to empathy_ft_handler_start_transfer() and
69 * the last signal, a ::transfer-error can be emitted, indicating that an
70 * error has happened in the operation. The message of the error is localized
