=head1 NAME
Mail::Server::IMAP4::Fetch - message info for IMAP protocol speed-up
=head1 SYNOPSIS
my $imap = Mail::Server::IMAP4::Fetch->new($msg);
print $imap->fetchBody(1); # for FETCH BODYSTRUCTURE
print $imap->fetchBody; # for FETCH BODY
print $imap->fetchEnvelope; # for FETCH ENVELOPE
print $imap->fetchSize;
=head1 DESCRIPTION
Create a new object hierarchy, which contains information to capture
the most important details about the message. The object can be used
to speed-up IMAP-server implementations, as L<Mail::Box::Netzwert>.
The object used here is a simplified representation of a
L<Mail::Box::Message|Mail::Box::Message> object. It does not maintain headers and does
not refer to the folder. It only works with messages stored in a file.
Therefore, this object can be frozen by L<Storable> if you want to.

=head2 IMAP Commands
=over 4
=item $obj-E<gt>B<fetchBody>($extended)
Returns one string, representing the message's structure as defined by
the IMAP protocol. The boolean argument indicates whether you like to
have the $extended information, as the imap command 'FETCH BODYSTRUCTURE'
defines or the limited information of 'FETCH BODY'.
=item $obj-E<gt>B<fetchEnvelope>()
Returns a string representation of some header information.
=item $obj-E<gt>B<fetchSize>()
Returns the size of the message body.
=item $obj-E<gt>B<part>( [$partnr] )
The partnummer is a list of dot-separated positive integers, numbering
(nested) parts in multi-part message bodies. By default, the info of
the main message is returned.
example:
my $partinfo = $msg->info->part('1.2.1');
print $msg->info->part('3.3')->fetchBody;
=item $obj-E<gt>B<printStructure>( [<$fh|undef>, [$number]] )
Print the structure of the fetch data to the specified $fh or the
selected filehandle. When explicitly C<undef> is specified as handle,
then the output will be returned as string.
Only a limited set of the information is displayed.
example:
my $imap = ...;
$imap->printStructure(\*OUTPUT);
$imap->printStructure;
my $struct = $imap->printStructure(undef);
