METHODS

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

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

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

       Mail::Message::Field::Structured->from($field, %options)
           Inherited, see "Constructors" in Mail::Message::Field::Full

       Mail::Message::Field::Structured->new($data)
           •   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, OPTIONS

               A set of values which shape the line.

           The NAME is a wellformed header name (you may use wellformedName()) to be sure about
           the casing.  The BODY is a string, one object, or an ref-array of objects.  In case of
           objects, they must fit to the constructor of the field: the types which are accepted
           may differ.  The optional ATTRIBUTE list contains Mail::Message::Field::Attribute
           objects.  Finally, there are some OPTIONS.

            -Option    --Defined in                --Default
             attributes                              []
             charset     Mail::Message::Field::Full  undef
             datum                                   undef
             encoding    Mail::Message::Field::Full  'q'
             force       Mail::Message::Field::Full  false
             language    Mail::Message::Field::Full  undef
             log         Mail::Reporter              'WARNINGS'
             trace       Mail::Reporter              'WARNINGS'

           attributes => ATTRS
             There are various ways to specify these attributes: pass a reference to an array
             which list of key-value pairs representing attributes, or reference to a hash
             containing these pairs, or an array with Mail::Message::Field::Attribute objects.

           charset => STRING
           datum => STRING
             The method name body is very confusing, even in the RFC.  In MailBox, for historical
             reasons, body() returns the part of the field contents before the first semi-colon.
             foldedBody() and unfoldedBody() address the whole field.

             There is no common name for the piece of data before the parameters (attributes) in
             the field-content mentioned in the RFCs, so let's call it datum.

           encoding => 'q'|'Q'|'b'|'B'
           force => BOOLEAN
           language => STRING
           log => LEVEL
           trace => LEVEL

           example: of a structured field

            my @attrs   = (Mail::Message::Field::Attribute->new(...), ...);
            my @options = (extra => 'the color blue');
            my $t = Mail::Message::Field::Full->new(To => \@addrs, @attrs, @options);

   Access to the content
       Extends "Access to the content" in Mail::Message::Field::Full.

       $obj->addresses()
           Inherited, see "Access to the content" in Mail::Message::Field

       $obj->attrPairs()
           Returns a list with attribute name and value pairs.

       $obj->attribute( $object|<STRING, %options>|<$name,$value,%options> )
           Add an attribute to the field.  The attributes are added left-to-right into the string
           representation of the field, although the order of the attributes is un-important,
           according to the RFCs.

           You may pass a fully prepared Mail::Message::Field::Attribute $object, if you like to
           do all preparations for correct representation of the data yourself.  You may also
           pass one STRING, which is a fully prepared attribute.  This STRING will not be
           changed, so be careful about quoting and encodings.

           As third possibility, you can specify an attribute $name and its $value.  An attribute
           object will be created for you implicitly in both cases where such object is not
           supplied, passing the %options.  See Mail::Message::Field::Attribute::new() about the
           available %options.

           The attribute object is returned, however, when continuations are used this may be an
           object you already know about.  "undef" is returned when construction fails (when the
           attribute is incorrect).

           example:

            $f->attribute(filename => 'passwd');
            $f->attribute(filename => 'passwd', use_continuations => 0);

            my $attr = Mail::Message::Field::Attribute->new(...);
            $f->attribute($attr);

       $obj->attributes()
           Returns a list with all attributes, which are all Mail::Message::Field::Attribute
           objects.  The attributes are not ordered in any way.  The list may be empty.  Double
           attributes or continuations are folded into one.

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 charset '$charset'
           The field is created with an utf8 string which only contains data from the specified
           character set.  However, that character set can never be a valid name because it
           contains characters which are not permitted.

       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.

       Warning: Illegal character in language '$lang'
           The field is created with data which is specified to be in a certain language,
           however, the name of the language cannot be valid: it contains characters which are
           not permitted by the RFCs.

       Warning: Illegal encoding '$encoding', used 'q'
           The RFCs only permit base64 ("b " or "B ") or quoted-printable ("q" or "Q") encoding.
           Other than these four options are illegal.

       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.
