#### Virtual methods

###### Camel.FolderClass.append_message_sync

Appends `message` to `folder`. Only the flag and tag data from `info` are used. If `info` is `NULL`, no flags or tags will be set.

since: 3.0

###### Camel.FolderClass.changed

Emits the `CamelFolder::changed` signal from an idle source on the main loop. The idle source’s priority is #G_PRIORITY_LOW.

since: 2.32

###### Camel.FolderClass.cmp_uids

Compares two uids. The return value meaning is the same as in any other compare function.

since: 2.28

###### Camel.FolderClass.delete_

No description available.

###### Camel.FolderClass.deleted

No description available.

###### Camel.FolderClass.dup_headers_sync

Reads headers of a message with the `uid` and returns it in the `out_headers`. Free the headers with camel_name_value_array_free(), when no longer needed.

since: 3.58

###### Camel.FolderClass.dup_uids

Duplicates a list of UIDs available in the `folder`. Free the array with g_ptr_array_unref(), when no longer needed.

since: 3.58

###### Camel.FolderClass.dup_uncached_uids

Returns the known-uncached uids from a list of uids. It may return uids which are locally cached but should never filter out a uid which is not locally cached.

since: 3.58

###### Camel.FolderClass.expunge_sync

Deletes messages which have been marked as “DELETED”.

since: 3.0

###### Camel.FolderClass.freeze

Freezes the folder so that a series of operation can be performed without “folder_changed” signals being emitted. When the folder is later thawed with camel_folder_thaw(), the suppressed signals will be emitted.

###### Camel.FolderClass.get_filename

No description available.

since: 2.26

###### Camel.FolderClass.get_full_display_name

Similar to the camel_folder_get_full_name(), only returning full path to the `folder` suitable for the display to a user.

###### Camel.FolderClass.get_message_cached

Gets the message corresponding to `message_uid` from the `folder` cache, if available locally. This should not do any network I/O, only check if message is already downloaded and return it quickly, not being blocked by the folder’s lock. Returning NULL is not considered as an error, it just means that the message is still to-be-downloaded.

since: 3.58

###### Camel.FolderClass.search_header_sync

Search the folder for messages with header `header_name`, which either contains the `words` or, when the `words` is empty or `NULL`, the header exists in the message. The list of satisfying message UIDs is returned in the `out_uids`. The result list can be empty, meaning no such message exists.
