NAME
Mail::Message::Field::Unstructured - smart unstructured field
INHERITANCE
Mail::Message::Field::Unstructured
is a Mail::Message::Field::Full
is a Mail::Message::Field
is a Mail::Reporter
SYNOPSIS
my $f = Mail::Message::Field::Unstructured->new('Comments', 'hi!');
DESCRIPTION
Unstructured fields do contain information which is not restricted in any way. RFC2822 defines some
unstructured fields, but by default all unknown fields are unstructured as well. Things like attributes
and comments have no meaning for unstructured fields, but encoding does.

$class->new($data)
When the $data is specified as single line, the content part is considered to be correcly (character)
encoded and escaped. Typically, it is a line as read from file. The folding of the line is kept as
is.
In case more than one argument is provided, the second is considered the BODY. Attributes and other
special things are not defined for unstructured fields, and therefore not valid options. The BODY
can be a single string, a single OBJECT, or an array of OBJECTS. The objects are stringified (into a
comma separated list). Each BODY element is interpreted with the specified encoding.
When the BODY is empty, the construction of the object fails: "undef" is returned. Improves base,

DIAGNOSTICS
Warning: Attributes are not supported for unstructured fields
Cast by new()
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. Cast by toInt()
Error: Field name too long (max $length), in '$name'
It is not specified in the RFCs how long a field name can be, but at least it should be a few
characters shorter than the line wrap. Cast by fold()
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. Cast by encode()
Warning: Illegal character in field name $name
A new field is being created which does contain characters not permitted by the RFCs. Using this
field in messages may break other e-mail clients or transfer agents, and therefore mutulate or
extinguish your message. Cast by consume()
Warning: Illegal character in language '$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. Cast by
encode()
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. Cast by encode()
Warning: No extras for unstructured fields
Cast by new()
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. Cast by notImplemented()
