\modulesynopsis{Read various mailbox formats.}
|
|
|
|
|
|
|
|
This module defines a number of classes that allow easy and uniform
|
|
access to mail messages in a (\UNIX{}) mailbox.
|
|
|
|
\begin{classdesc}{UnixMailbox}{fp}
|
|
Access a classic \UNIX{}-style mailbox, where all messages are contained
|
|
in a single file and separated by ``From name time'' lines.
|
|
The file object \var{fp} points to the mailbox file.
|
|
\end{classdesc}
|
|
|
|
\begin{classdesc}{MmdfMailbox}{fp}
|
|
Access an MMDF-style mailbox, where all messages are contained
|
|
in a single file and separated by lines consisting of 4 control-A
|
|
characters. The file object \var{fp} points to the mailbox file.
|
|
\end{classdesc}
|
|
|
|
\begin{classdesc}{MHMailbox}{dirname}
|
|
Access an MH mailbox, a directory with each message in a separate
|
|
file with a numeric name.
|
|
The name of the mailbox directory is passed in \var{dirname}.
|
|
\end{classdesc}
|
|
|
|
\subsection{Mailbox Objects}
|
|
\label{mailbox-objects}
|
|
|
|
All implementations of Mailbox objects have one externally visible
|
|
method:
|
|
|
|
\begin{methoddesc}[mailbox]{next}{}
|
|
Return the next message in the mailbox, as a \class{rfc822.Message} object.
|
|
Depending on the mailbox implementation the \var{fp} attribute of this
|
|
object may be a true file object or a class instance simulating a file object,
|
|
taking care of things like message boundaries if multiple mail messages are
|
|
contained in a single file, etc.
|
|
\end{methoddesc}
