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

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: "" stringification: Inherited, see "OVERLOADED" in Mail::Message::Field
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.

Constructors¶

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

$obj->clone(): Inherited, see "Constructors" in Mail::Message::Field
$class->new($line | ($name, ($body|$object|\@objects), [@attributes], [\%options|\@options])): 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
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|$object|\@objects), [@attributes], [\%options|\@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 string, one $object, or an ARRAY of @objects. See Mail::Message::Field. Improves base, see "Constructors" in Mail::Message::Field

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

attributes => \@attributes|\%attributes: An ARRAY with contains 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 => $text: 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. 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 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()
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()
