NAME

       Mail::Server::IMAP4::Fetch - message info for IMAP protocol speed-up

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;

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 Mail::Box::Netzwert.

       The object used here is a simplified representation of a 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 Storable if you want to.

METHODS

   Attributes

       $obj->headLocation()
       $obj->partLocation()

   IMAP Commands
       $obj->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'.

       $obj->fetchEnvelope()
           Returns a string representation of some header information.

       $obj->fetchSize()
           Returns the size of the message body.

       $obj->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;

       $obj->printStructure([FILEHANDLE|undef, [NUMBER]])
           Print the structure of the fetch data to the specified FILEHANDLE or the selected
           filehandle.  When explicitly "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);
