67           Inherited, see "Constructors" in Mail::Message::Field::Full
68
69       Mail::Message::Field::Structured->new($data)
70           ·   new LINE
71
72               Pass a LINE as it could be found in a file: a (possibly folded)
73               line which is terminated by a new-line.
74
75           ·   new NAME, BODY, OPTIONS
76
77               A set of values which shape the line.
78
79           The NAME is a wellformed header name (you may use wellformedName())
80           to be sure about the casing.  The BODY is a string, one object, or
81           an ref-array of objects.  In case of objects, they must fit to the
82           constructor of the field: the types which are accepted may differ.
83           The optional ATTRIBUTE list contains
84           Mail::Message::Field::Attribute objects.  Finally, there are some
85           OPTIONS.
86
87            -Option    --Defined in                --Default
88             attributes                              []
89             charset     Mail::Message::Field::Full  undef
90             datum                                   undef
91             encoding    Mail::Message::Field::Full  'q'
92             force       Mail::Message::Field::Full  false
93             language    Mail::Message::Field::Full  undef
94             log         Mail::Reporter              'WARNINGS'
95             trace       Mail::Reporter              'WARNINGS'
96
97           attributes => ATTRS
98             There are various ways to specify these attributes: pass a
99             reference to an array which list of key-value pairs representing
100             attributes, or reference to a hash containing these pairs, or an
101             array with Mail::Message::Field::Attribute objects.
102
103           charset => STRING
104           datum => STRING
105             The method name body is very confusing, even in the RFC.  In
106             MailBox, for historical reasons, body() returns the part of the
107             field contents before the first semi-colon.  foldedBody() and
108             unfoldedBody() address the whole field.
109
110             There is no common name for the piece of data before the
111             parameters (attributes) in the field-content mentioned in the
112             RFCs, so let's call it datum.
113
114           encoding => 'q'|'Q'|'b'|'B'
115           force => BOOLEAN
116           language => STRING
117           log => LEVEL
118           trace => LEVEL

120           example: of a structured field
121
122            my @attrs   = (Mail::Message::Field::Attribute->new(...), ...);
123            my @options = (extra => 'the color blue');
124            my $t = Mail::Message::Field::Full->new(To => \@addrs, @attrs, @options);

190
191       $obj->attrPairs()
192           Returns a list with attribute name and value pairs.
193
194       $obj->attribute( $object|<STRING, %options>|<$name,$value,%options> )
195           Add an attribute to the field.  The attributes are added left-to-
196           right into the string representation of the field, although the
197           order of the attributes is un-important, according to the RFCs.
198
199           You may pass a fully prepared Mail::Message::Field::Attribute
200           $object, if you like to do all preparations for correct
201           representation of the data yourself.  You may also pass one STRING,
202           which is a fully prepared attribute.  This STRING will not be
203           changed, so be careful about quoting and encodings.
204
205           As third possibility, you can specify an attribute $name and its
206           $value.  An attribute object will be created for you implicitly in
207           both cases where such object is not supplied, passing the %options.
208           See Mail::Message::Field::Attribute::new() about the available
209           %options.
210
211           The attribute object is returned, however, when continuations are
212           used this may be an object you already know about.  "undef" is
213           returned when construction fails (when the attribute is incorrect).
214
215           example:
216
217            $f->attribute(filename => 'passwd');
218            $f->attribute(filename => 'passwd', use_continuations => 0);
219
220            my $attr = Mail::Message::Field::Attribute->new(...);
221            $f->attribute($attr);
222
223       $obj->attributes()
224           Returns a list with all attributes, which are all
225           Mail::Message::Field::Attribute objects.  The attributes are not
226           ordered in any way.  The list may be empty.  Double attributes or
227           continuations are folded into one.

DIAGNOSTICS

369       Warning: Field content is not numerical: $content
370           The numeric value of a field is requested (for instance the "Lines"
371           or "Content-Length" fields should be numerical), however the data
372           contains weird characters.
373
374       Warning: Illegal character in charset '$charset'
375           The field is created with an utf8 string which only contains data
376           from the specified character set.  However, that character set can
377           never be a valid name because it contains characters which are not
378           permitted.
379
380       Warning: Illegal character in field name $name
381           A new field is being created which does contain characters not
382           permitted by the RFCs.  Using this field in messages may break
383           other e-mail clients or transfer agents, and therefore mutulate or
384           extinguish your message.
385
386       Warning: Illegal character in language '$lang'
387           The field is created with data which is specified to be in a
388           certain language, however, the name of the language cannot be
389           valid: it contains characters which are not permitted by the RFCs.
390
391       Warning: Illegal encoding '$encoding', used 'q'
392           The RFCs only permit base64 ("b " or "B ") or quoted-printable ("q"
393           or "Q") encoding.  Other than these four options are illegal.
394
395       Error: Package $package does not implement $method.
396           Fatal error: the specific package (or one of its superclasses) does
397           not implement this method where it should. This message means that
398           some other related classes do implement this method however the
399           class at hand does not.  Probably you should investigate this and
400           probably inform the author of the package.
