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

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).

Mail::Message::Body::Multipart->new(OPTIONS)
Option --Defined in --Default
based_on Mail::Message::Body undef
boundary undef
charset Mail::Message::Body 'PERL' or <undef>
checked Mail::Message::Body <false>
data Mail::Message::Body undef
description Mail::Message::Body undef

transfer_encoding Mail::Message::Body 'none'
. 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
. 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
. 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
$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->check
See "Constructing a body" in Mail::Message::Body::Encode
$obj->concatenate(COMPONENTS)
See "Constructing a body" in Mail::Message::Body::Construct
$obj->decoded(OPTIONS)
See "Constructing a body" in Mail::Message::Body
$obj->encode(OPTIONS)
See "Constructing a body" in Mail::Message::Body::Encode
$obj->encoded
See "Constructing a body" in Mail::Message::Body::Encode
$obj->eol(['CR'|'LF'|'CRLF'|'NATIVE'])
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.
$obj->stripSignature(OPTIONS)
Removes all parts which contains data usually defined as being
signature. The MIME::Type module provides this knowledge. A new
multipart is returned, containing the remaining parts. No OPTIONS
are defined yet, although some may be specified, because this
method overrules the "stripSignature" method for normal bodies.
Option --Defined in --Default
max_lines Mail::Message::Body::Construct 10
pattern Mail::Message::Body::Construct qr/^--\s?$/
result_type Mail::Message::Body::Construct <same as current>

Access to the payload
$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
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
See "Access to the payload" in Mail::Message::Body
$obj->lines
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.
$obj->print([FILEHANDLE])

DETAILSDIAGNOSTICS
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 acceptible.
