NAME
Mail::Message::Body::Multipart - body of a message with attachments
INHERITANCE
Mail::Message::Body::Multipart
is a Mail::Message::Body
is a Mail::Reporter
SYNOPSIS
See Mail::Message::Body
if($body->isMultipart) {
my @attachments = $body->parts;
my $attachment3 = $body->part(2);
my $before = $body->preamble;
my $after = $body->epilogue;
$body->part(1)->delete;
}
DESCRIPTION
The body (content) of a message can be stored in various ways. In this manual-page you
find the description of extra functionality you have when a message contains attachments
(parts).
Extends "DESCRIPTION" in Mail::Message::Body.
OVERLOADED
Extends "OVERLOADED" in Mail::Message::Body.
overload: ""
Inherited, see "OVERLOADED" in Mail::Message::Body
overload: '==' and '!='
Inherited, see "OVERLOADED" in Mail::Message::Body
overload: @{}
Inherited, see "OVERLOADED" in Mail::Message::Body
overload: bool
Inherited, see "OVERLOADED" in Mail::Message::Body
METHODS
Extends "METHODS" in Mail::Message::Body.
Constructors
Extends "Constructors" in Mail::Message::Body.

based_on => BODY
boundary => STRING
Separator to be used between parts of the message. This separator must be unique in
case the message contains nested multiparts (which are not unusual). If "undef", a
nice unique boundary will be generated.
charset => CHARSET|'PERL'
checked => BOOLEAN
content_id => STRING
data => ARRAY-OF-LINES | STRING
description => STRING|FIELD
disposition => STRING|FIELD
eol => 'CR'|'LF'|'CRLF'|'NATIVE'
epilogue => BODY|STRING
The text which is included in the main body after the final boundary. This is
usually empty, and has no meaning.
Provide a BODY object or a STRING which will automatically translated into a
"text/plain" body.
file => FILENAME|FILEHANDLE|IOHANDLE
filename => FILENAME
log => LEVEL
message => MESSAGE
mime_type => STRING|FIELD|MIME
modified => BOOLEAN
parts => ARRAY-OF-(MESSAGES|BODIES)
Specifies an initial list of parts in this body. These may be full MESSAGES, or
BODIES which transformed into messages before use. Each message is coerced into a
Mail::Message::Part object.
MIME::Entity and Mail::Internet objects are acceptable in the list, because they are
coercible into Mail::Message::Part's. Values of "undef" will be skipped silently.
preamble => BODY|STRING
The text which is included in the body before the first part. It is common use to
include a text to warn the user that the message is a multipart. However, this was
useful in earlier days: most mail agents are very capable in warning the user
themselves.
Provide a BODY object or a STRING which will automatically translated into a
text/plain body.
trace => LEVEL
transfer_encoding => STRING|FIELD
example:
my $intro = Mail::Message::Body->new(data => ['part one']);
my $pgp = Mail::Message::Body->new(data => ['part three']);
my $body = Mail::Message::Body::Multipart->new
( boundary => time . '--it-s-mine'
, preamble => "This is a multi-part message in MIME format.\n\n"
, parts => [ $intro, $folder->message(3)->decoded, $pgp ]
);
Constructing a body
Extends "Constructing a body" in Mail::Message::Body.
$obj->attach($messages|$bodies)
Attach a list of $messages to this multipart. A new body is returned. When you
specify $bodies, they will first be translated into real messages. MIME::Entity and
Mail::Internet objects may be specified too. In any case, the parts will be coerced
into Mail::Message::Part's.

$obj->eol( ['CR'|'LF'|'CRLF'|'NATIVE'] )
Inherited, see "Constructing a body" in Mail::Message::Body
$obj->foreachComponent(CODE)
Execute the CODE for each component of the message: the preamble, the epilogue, and
each of the parts.
Each component is a body and is passed as second argument to the CODE. The first
argument is a reference to this multi-parted body. The CODE returns a body object.
When any of the returned bodies differs from the body which was passed, then a new
multi-part body will be returned. Reference to the not-changed bodies and the changed
bodies will be included in that new multi-part.
example:
my $checked = $multi->foreachComponent(sub {$_[1]->check});
$obj->foreachLine((CODE))
It is NOT possible to call some code for each line of a multipart, because that would
not only inflict damage to the body of each message part, but also to the headers and
the part separators.
$obj->stripSignature(%options)
Removes all parts which contains data usually defined as being signature. The
MIME::Type module provides this knowledge. A new multipart is returned, containing
the remaining parts. No %options are defined yet, although some may be specified,
because this method overrules the "stripSignature" method for normal bodies.

Access to the payload
Extends "Access to the payload" in Mail::Message::Body.
$obj->boundary( [STRING] )
Returns the boundary which is used to separate the parts in this body. If none was
read from file, then one will be assigned. With STRING you explicitly set the
boundary to be used.
$obj->endsOnNewline()
Inherited, see "Access to the payload" in Mail::Message::Body
$obj->epilogue()
Returns the epilogue; the text after the last message part (after the last real
attachment). The epilogue is stored in a BODY object, and its encoding is taken from
the general multipart header.
$obj->file()
Inherited, see "Access to the payload" in Mail::Message::Body
$obj->lines()
Inherited, see "Access to the payload" in Mail::Message::Body
$obj->part($index)
Returns only the part with the specified $index. You may use a negative value here,
which counts from the back in the list. Parts which are flagged to be deleted are
included in the count.
example:
$message->body->part(2)->print;
$body->part(1)->delete;
$obj->parts( [<'ALL'|'ACTIVE'|'DELETED'|'RECURSE'|$filter>] )
Return all parts by default, or when ALL is specified. "ACTIVE" returns the parts
which are not flagged for deletion, as opposite to "DELETED". "RECURSE" descents into
all nested multiparts to collect all parts.
You may also specify a code reference which is called for each nested part. The first
argument will be the message part. When the code returns true, the part is
incorporated in the return list.
example:
print "Number of attachments: ",
scalar $message->body->parts('ACTIVE');
foreach my $part ($message->body->parts) {
print "Type: ", $part->get('Content-Type');
}
$obj->preamble()
Returns the preamble; the text before the first message part (before the first real
attachment). The preamble is stored in a BODY object, and its encoding is taken from
the multipart header.

DIAGNOSTICS
Warning: Charset $name is not known
The encoding or decoding of a message body encounters a character set which is not
understood by Perl's Encode module.
Error: Data not convertible to a message (type is $type)
An object which is not coercable into a Mail::Message::Part object was passed to the
initiation. The data is ignored.
Warning: No decoder defined for transfer encoding $name.
The data (message body) is encoded in a way which is not currently understood,
therefore no decoding (or recoding) can take place.
Warning: No encoder defined for transfer encoding $name.
The data (message body) has been decoded, but the required encoding is unknown. The
decoded data is returned.
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: Unknown criterium $what to select parts.
Valid choices fdr part selections are "ALL", "ACTIVE", "DELETED", "RECURSE" or a code
reference. However, some other argument was passed.
Warning: Unknown line terminator $eol ignored
Error: You cannot use foreachLine on a multipart
foreachLine() should be used on decoded message bodies only, because it would attempt
to modify part-headers and separators as well, which is clearly not acceptable.
