rb_transfer_target_build_dest_uri ()

char *
rb_transfer_target_build_dest_uri (RBTransferTarget *target,
                                   RhythmDBEntry *entry,
                                   const char *media_type,
                                   const char *extension);

Constructs a URI to use as the destination for a transfer or transcoding operation. The URI may be on the device itself, if the device is mounted into the normal filesystem or through gvfs, or it may be a temporary location used to store the file before uploading it to the device.

The destination URI should conform to the device's normal URI format, and should use the provided extension instead of the extension from the source entry.

rb_transfer_target_track_added ()

void
rb_transfer_target_track_added (RBTransferTarget *target,
                                RhythmDBEntry *entry,
                                const char *uri,
                                guint64 filesize,
                                const char *media_type);

This is called when a transfer to the target has completed. If the source's track_added method returns TRUE, the destination URI will be added to the database using the entry type for the device.

If the target uses a temporary area as the destination for transfers, it can instead upload the destination file to the device and create an entry for it, then return FALSE.

rb_transfer_target_track_add_error ()

void
rb_transfer_target_track_add_error (RBTransferTarget *target,
                                    RhythmDBEntry *entry,
                                    const char *uri,
                                    GError *error);

This is called when a transfer fails. If the source's impl_track_add_error implementation returns TRUE, an error dialog will be displayed to the user containing the error message, unless the error indicates that the destination file already exists.

rb_transfer_target_should_transfer ()

gboolean
rb_transfer_target_should_transfer (RBTransferTarget *target,
                                    RhythmDBEntry *entry);

Checks whether entry should be transferred to the target. The target can check whether a matching entry already exists on the device, for instance. rb_transfer_target_check_duplicate may form part of an implementation. If this method returns FALSE, the entry will be skipped.

rb_transfer_target_get_format_descriptions ()

GList *
rb_transfer_target_get_format_descriptions
                               (RBTransferTarget *target);

Returns a GList of allocated media format descriptions for the formats supported by the target. The list and the strings it holds must be freed by the caller.

rb_transfer_target_check_category ()

gboolean
rb_transfer_target_check_category (RBTransferTarget *target,
                                   RhythmDBEntry *entry);

This checks that the entry type of entry is in a suitable category for transfer. This can be used to implement should_transfer .

rb_transfer_target_check_duplicate ()

gboolean
rb_transfer_target_check_duplicate (RBTransferTarget *target,
                                    RhythmDBEntry *entry);

This checks for an existing entry in the target that matches the title, album, artist, and track number of the entry being considered. This can be used to implement should_transfer .

rb_transfer_target_transfer ()

RBTrackTransferBatch *
rb_transfer_target_transfer (RBTransferTarget *target,
                             GSettings *settings,
                             GList *entries,
                             gboolean defer);

Starts tranferring entries to the target. This returns the RBTrackTransferBatch that it starts, so the caller can track the progress of the transfer, or NULL if the target doesn't want any of the entries.
