NAME

       Mail::Message::Field::Fast - one line of a message header

INHERITANCE

        Mail::Message::Field::Fast
          is a Mail::Message::Field
          is a Mail::Reporter

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.

METHODS

       See documentation in the base class.

   Constructors
       See documentation in the base class.

       $obj->clone()
           See "Constructors" in Mail::Message::Field

       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:

           •   new LINE

               Pass a LINE as it could be found in a file: a (possibly folded) line which is
               terminated by a new-line.

           •   new NAME, (BODY|OBJECTS), [ATTRIBUTES]

               A set of values which shape the line.

           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.

            -Option--Defined in     --Default
             log     Mail::Reporter   <disabled>
             trace   Mail::Reporter   <disabled>

           log => LEVEL
           trace => LEVEL

           example:

            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@example.com');

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

DIAGNOSTICS

       Warning: Field content is not numerical: $content
           The numeric value of a field is requested (for instance the "Lines" or
           "Content-Length" fields should be numerical), however the data contains weird
           characters.

       Warning: Illegal character in field name $name
           A new field is being created which does contain characters not permitted by the RFCs.
           Using this field in messages may break other e-mail clients or transfer agents, and
           therefore mutulate or extinguish your message.

       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.
