SYNOPSIS
See Mail::Message::Body
if($body->isMultipart) {

DESCRIPTION

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.

METHODS
Extends "METHODS" 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'|<undef>
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.

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.
