Instances

Eq Flag # |
Methods (==) :: Flag -> Flag -> Bool # (/=) :: Flag -> Flag -> Bool #
Show Flag # |
Methods showsPrec :: Int -> Flag -> ShowS # show :: Flag -> String # showList :: [Flag] -> ShowS #

type Flags = [Flag] #

Convenience shortcut

type Message = String #

A Message is represented as a simple String.

class (Show a, Show b, Eq b) => MailboxReader a b where #

Main class for readable mailboxes.

The mailbox object a represents zero or more `Message`s. Each message has a unique identifier b in a format specific to each given mailbox. This identifier may or may not be persistent.

Functions which return a list are encouraged -- but not guaranteed -- to do so lazily.

Implementing classes must provide, at minimum, `getAll`.

getAll

Methods

listIDs :: a -> IO [b] #

Returns a list of all unique identifiers.

listMessageFlags :: a -> IO [(b, Flags)] #

Returns a list of all unique identifiers as well as all flags.

getAll :: a -> IO [(b, Flags, Message)] #

Returns a list of all messages, including their content, flags, and unique identifiers.

getMessages :: a -> [b] -> IO [(b, Flags, Message)] #

Returns information about specific messages.

class MailboxReader a b => MailboxWriter a b where #
