Petrilli}{petrilli@amber.org} + +This module defines the class \class{MimeWriter}. The +\class{MimeWriter} class implements a basic formatter for creating +MIME multi-part files. It doesn't seek around the output file nor +does it use large amounts of buffer space. You must write the parts +out in the order that they should occur in the final +file. \class{MimeWriter} does buffer the headers you add, allowing you +to rearrange their order. + +\begin{classdesc}{MimeWriter}{fp} +Return a new instance of the \class{MimeWriter} class. The only +argument passed, \var{fp}, is a file object to be used for +writing. Note that a \class{StringIO} object could also be used. +\end{classdesc} + + +\subsection{MimeWriter Objects \label{MimeWriter-objects}} + + +\class{MimeWriter} instances have the following methods: + +\begin{methoddesc}{addheader}{key, value\optional{, prefix}} +Add a header line to the MIME message. The \var{key} is the name of +the header, where the \var{value} obviously provides the value of the +header. The optional argument \var{prefix} determines where the header +is inserted; \samp{0} means append at the end, \samp{1} is insert at +the start. The default is to append. +\end{methoddesc} + +\begin{methoddesc}{flushheaders}{} +Causes all headers accumulated so far to be written out (and +forgotten). This is useful if you don't need a body part at all, +e.g.\ for a subpart of type \mimetype{message/rfc822} that's (mis)used +to store some header-like information. +\end{methoddesc} + +\begin{methoddesc}{startbody}{ctype\optional{, plist\optional{, prefix}}} +Returns a file-like object which can be used to write to the +body of the message. The content-type is set to the provided +\var{ctype}, and the optional parameter \var{plist} provides +additional parameters for the content-type declaration. \var{prefix} +functions as in \method{addheader()} except that the default is to +insert at the start. +\end{methoddesc} + +\begin{methoddesc}{startmultipartbody}{subtype\optional{, + boundary\optional{, plist\optional{, prefix}}}} +Returns a file-like object which can be used to write to the +body of the message. Additionally, this method initializes the +multi-part code, where \var{subtype} provides the mutlipart subtype, +\var{boundary} may provide a user-defined boundary specification, and +\var{plist} provides optional parameters for the subtype. +\var{prefix} functions as in \method{startbody()}. Subparts should be +created using \method{nextpart()}. +\end{methoddesc} + +\begin{methoddesc}{nextpart}{} +Returns a new instance of \class{MimeWriter} which represents an +individual part in a multipart message. This may be used to write the +part as well as used for creating recursively complex multipart +messages. The message must first be initialized with +\method{startmultipartbody()} before using \method{nextpart()}. +\end{methoddesc} + +\begin{methoddesc}{lastpart}{} +This is used to designate the last part of a multipart message, and +should \emph{always} be used when writing multipart messages. +\end{methoddesc} |
