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

$class->new(($line | $name, $body, @attributes), %options)

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, @attributes, %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 body object, or an ARRAY of body objects. In case of objects, they must fit to the constructor of the field: the types which are accepted may differ. The @attributes LIST contains Mail::Message::Field::Attribute objects. Finally, there are some %options. Improves base, see "METHODS" in Mail::Message::Field::Full

-Option    --Defined in                --Default
 attributes                              +[ ]
 charset     Mail::Message::Field::Full  undef

 language    Mail::Message::Field::Full  undef
 log         Mail::Reporter              'WARNINGS'
 trace       Mail::Reporter              'WARNINGS'

attributes => \@attributes|\%attributes

There are various ways to specify these attributes: pass an ARRAY which list of key-value pairs representing @attributes, or an HASH containing these pairs, or an ARRAY with Mail::Message::Field::Attribute objects.

charset => $charset

datum => $date

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 => $language

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);

Attributes

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

$obj->logSettings(): Inherited, see "Attributes" in Mail::Reporter

The field

Extends "The field" in Mail::Message::Field::Full.

$obj->Name(): Inherited, see "Access to the name" in Mail::Message::Field
$obj->name(): Inherited, see "Access to the name" in Mail::Message::Field
$obj->wellformedName( [STRING] ): Inherited, see "Access to the name" in Mail::Message::Field

Access to the body

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

$obj->body(): Inherited, see "Access to the body" in Mail::Message::Field
$obj->decodedBody(%options): Inherited, see "Access to the body" in Mail::Message::Field::Full

$obj->unfoldedBody( [$body, [$wrap]] ): Inherited, see "Access to the body" in Mail::Message::Field

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). Improves base, see "Access to the content" in Mail::Message::Field

» 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. Improves base, see "Access to the content" in Mail::Message::Field

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 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()
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()
