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