NAME

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

INHERITANCE

        Mail::Message::Field::Flex
          is a Mail::Message::Field
          is a Mail::Reporter

SYNOPSIS

DESCRIPTION

       This is the flexible implementation of a field: it can easily be extended because it
       stores its data in a hash and the constructor ("new") and initializer ("init") are split.
       However, you pay the price in performance.  Mail::Message::Field::Fast is faster (as the
       name predicts).

       Extends "DESCRIPTION" in Mail::Message::Field.

OVERLOADED

       Extends "OVERLOADED" in Mail::Message::Field.

       overload: ""
           Inherited, see "OVERLOADED" in Mail::Message::Field

       overload: 0+
           Inherited, see "OVERLOADED" in Mail::Message::Field

       overload: <=>
           Inherited, see "OVERLOADED" in Mail::Message::Field

       overload: bool
           Inherited, see "OVERLOADED" in Mail::Message::Field

       overload: cmp
           Inherited, see "OVERLOADED" in Mail::Message::Field

METHODS

       Extends "METHODS" in Mail::Message::Field.

   Constructors
       Extends "Constructors" in Mail::Message::Field.

       $obj->clone()
           Inherited, see "Constructors" in Mail::Message::Field

       Mail::Message::Field::Flex->new($data)
           If you stick to this flexible class of header fields, you have a bit more facilities
           than with Mail::Message::Field::Fast.  Amongst it, you can specify options with the
           creation.  Possible arguments:

           •   new LINE

               ass 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], OPTIONS

               A set of values which shape the line.

           To be able to distinguish the different parameters, you will have to specify the
           OPTIONS as ARRAY of option pairs, or HASH of options.  The ATTRIBUTES are a flat list
           of key-value pairs.  The body is specified as one BODY string, one OBJECT, or a
           reference to an array of OBJECTS.  See Mail::Message::Field:

            -Option    --Defined in     --Default
             attributes                   []
             comment                      undef
             log         Mail::Reporter   'WARNINGS'
             trace       Mail::Reporter   'WARNINGS'

           attributes => ATTRS
             Reference to array with list of key-value pairs representing attributes, or
             reference to a hash containing these pairs.  This is an alternative notation for
             specifying ATTRIBUTES directly as method arguments.

           comment => STRING
             A pre-formatted list of attributes.

           log => LEVEL
           trace => LEVEL

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.
