Mail::Message::Part(3)                     User Contributed Perl Documentation


NAME
       Mail::Message::Part - a part of a message, but a message by itself

INHERITANCE
        Mail::Message::Part
          is a Mail::Message
          is a Mail::Reporter

SYNOPSIS
        my Mail::Message $message = ...;
        if($message->isMultipart) {
           my Mail::Message::Part $part;

           foreach $part ($message->body->parts) {
              $part->print(\*OUT);
              my $attached_head = $part->head;
              my $attached_body = $part->body;      # encoded as read
              my $attached_body = $part->decoded;   # transfer-encoding removed
           }
        }

DESCRIPTION
       A "Mail::Message::Part" object contains a message which is included in
       the body of another message.  For instance attachments are parts.

       READ Mail::Message FIRST.  A part is a special message: it has a
       reference to its parent message, and will usually not be sub-classed
       into mail folder specific variants.

       Extends "DESCRIPTION" in Mail::Message.

METHODS
       Extends "METHODS" in Mail::Message.

   Constructors
       Extends "Constructors" in Mail::Message.

       $obj->clone(%options)
           Inherited, see "Constructors" in Mail::Message

       Mail::Message::Part->new(%options)
           Create a message part.

   Constructing a message
       Extends "Constructing a message" in Mail::Message.

           Mail::Message::Construct::Bounce

       Mail::Message::Part->build( [$message|$part|$body], $content )
           Inherited, see "Constructing a message" in
           Mail::Message::Construct::Build

       Mail::Message::Part->buildFromBody($body, $container, $headers)
           Shape a message part around a $body.  Bodies have information about
           their content in them, which is used to construct a header for the
           message.  Next to that, more $headers can be specified.  No headers
           are obligatory.  No extra headers are fabricated automatically.

           example:

            my $multi = Mail::Message::Body::Multipart->new;
            my $part  = Mail::Message::Part->buildFromBody($body, $multi);

       $obj->destruct()

           can be forcefully freed from memory.  Of course, you can delete()
           separate parts, which only sets a flag not to write a part again.
           Furthermore, you may cosider rebuild() to get rit of deleted parts.

DETAILS
       Extends "DETAILS" in Mail::Message.

DIAGNOSTICS
       Error: Cannot include forward source as $include.
           Unknown alternative for the forward(include).  Valid choices are
           "NO", "INLINE", "ATTACH", and "ENCAPSULATE".

       Error: Cannot include reply source as $include.
           Unknown alternative for the "include" option of reply().  Valid
           choices are "NO", "INLINE", and "ATTACH".

       Error: Method bounce requires To, Cc, or Bcc
           The message bounce() method forwards a received message off to
           someone else without modification; you must specified it's new
           destination.  If you have the urge not to specify any destination,
           you probably are looking for reply(). When you wish to modify the
           content, use forward().

       Error: Method forwardAttach requires a preamble
       Error: Method forwardEncapsulate requires a preamble
       Error: No address to create forwarded to.
           If a forward message is created, a destination address must be
           specified.

       Error: No default mailer found to send message.
           The message send() mechanism had not enough information to
           automatically find a mail transfer agent to sent this message.
           Specify a mailer explicitly using the "via" options.

       Error: No rebuild rule $name defined.
       Error: Only build() Mail::Message's; they are not in a folder yet
           You may wish to construct a message to be stored in a some kind of
           folder, but you need to do that in two steps.  First, create a
           normal Mail::Message, and then add it to the folder.  During this
           Mail::Box::addMessage() process, the message will get coerce()-d
           into the right message type, adding storage information and the
           like.

       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does
           not implement this method where it should. This message means that
           some other related classes do implement this method however the
           class at hand does not.  Probably you should investigate this and
           probably inform the author of the package.

       Error: You cannot destruct message parts, only whole messages
           Message parts can not be destructed per part: only whole messages
           can be forcefully freed from memory. Consider delete() or
           rebuild().
