Mail::Message::Part(3)

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

Constructing a message

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

$obj->bounce( [<$rg_object|%options>] )

Inherited, see "Constructing a message" in 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);

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().
