Mail::Message::Field::Unstructured(3pm)

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.

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

OVERLOADED¶

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

overload: "" stringification: Inherited, see "OVERLOADED" in Mail::Message::Field::Full
overload: 0+ numification: Inherited, see "OVERLOADED" in Mail::Message::Field
overload: <=> numeric comparison: Inherited, see "OVERLOADED" in Mail::Message::Field
overload: bool boolean: Inherited, see "OVERLOADED" in Mail::Message::Field
overload: cmp string comparison: Inherited, see "OVERLOADED" in Mail::Message::Field

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

$class->from($field, %options)

Inherited, see "Constructors" in Mail::Message::Field::Full

$class->new($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, see "METHODS" in Mail::Message::Field::Full

 -Option  --Defined in                --Default
  charset   Mail::Message::Field::Full  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'

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

» example:

  my $s = Mail::Message::Field::Unstructured->new('Comment', 'Hi!');
  # Use autodetect
  my $s = Mail::Message::Field::Full->new('Comment', 'Hi!');
  my $s = Mail::Message::Field::Full->new('Comment: Hi!');

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()
