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.

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;

$obj->printStructure( [<$fh|undef>, [$number]] )

Print the structure of the fetch data to the specified $fh 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);
