📋 SYNOPSIS

See Mail::Message::Field

📖 DESCRIPTION

This is the faster, but less flexible implementation of a header field. The data is stored in an array, and some hacks are made to speeds things up. Be gentle with me, and consider that each message contains many of these lines, so speed is very important here.

Mail::Message::Field::Fast->new($data)

The constructor of this object does not follow the usual practise within the Mail::Box suite: it does not use the constructor Mail::Reporter::new(). Therefor it has no logging or tracing facilities.

The method can be used in one of the following ways:

Create a new header field object. Specify the whole LINE at once, and it will be split-up for you. I case you already have the parts of the header line, you may specify them separately as NAME and BODY.

In case you specify a single OBJECT, or a reference to an array of OBJECTS, these objects are processed to become suitable to fill a field, usually by simple strification. When you specify one or more Mail::Address objects, these are transformed into a string using their "format" method. You may also add one Mail::Message::Field, whose body is taken. In case of an array, the elements are joined into one string with a comma.

ATTRIBUTES can be exactly one string which may contain multiple attributes at once, quoted and formatted as required in RFC2822. As alternative, list of key-value pairs can be used. In this case, the values will get quoted if needed and everything formatted as the protocol demands.

Examples:

my $mime = Mail::Message::Field->new(
    'Content-Type: text/plain; charset=US-ASCII');

my $mime = Mail::Message::Field->new(
    'Content-Type' => 'text/plain; charset=US-ASCII');

my $mime = Mail::Message::Field->new(
    'Content-Type' => 'text/plain', 'charset=US-ASCII');

my $mime = Mail::Message::Field->new(
    'Content-Type' => 'text/plain', charset => 'Latin1');

my $mime = Mail::Message::Field->new(
    To => Mail::Address->new('My', 'me AT example.com');

my $mime = Mail::Message::Field->new(
    Cc => [ Mail::Address->new('You', 'you AT example.com')
          , Mail::Address->new('His', 'he AT example.com')
          ]);

But in practice, you can simply call

my $head = Mail::Message::Head->new;
$head->add( 'Content-Type' => 'text/plain'
           , charset => 'utf8');

which implicitly calls this constructor (when needed). You can specify the same things for Mail::Message::Head::Complete::add() as this "new" accepts.
