$obj->clone()
Make a copy of this object. The collected fieldnames are copied and the list type information. No
deep copy is made for the header: this is only copied as reference.
$obj->from($head|$message)
Create a group of fields based on the specified $message or message $head. This may return one or
more of the objects, which depends on the type of group. Mailing list fields are all stored in one
object, where resent and spam groups can appear more than once.
$obj->implementedTypes()
Mail::Message::Head::FieldGroup->implementedTypes()
Returns a list of strings containing all possible return values for type().
Mail::Message::Head::FieldGroup->new($fields, %options)
Construct an object which maintains one set of header $fields. The $fields may be specified as
"Mail::Message::Field" objects or as key-value pairs. The %options and $fields (as key-value pair)
can be mixed: they are distinguished by their name, where the fields always start with a capital.
The field objects must aways lead the %options.
-Option --Defined in --Default
head undef
log Mail::Reporter 'WARNINGS'
software undef
trace Mail::Reporter 'WARNINGS'
type undef
version undef
head => HEAD
The header HEAD object is used to store the grouped fields in. If no header is specified, a
Mail::Message::Head::Partial is created for you. If you wish to scan the existing fields in a
header, then use the from() method.
log => LEVEL
software => STRING
Name of the software which produced the fields.
trace => LEVEL
type => STRING
Group name for the fields. Often the same, or close to the same STRING, as the "software" option
contains.
version => STRING
Version number for the software which produced the fields.
Theheader
$obj->add( <$field, $value> | $object )
Add a field to the header, using the field group. When the field group is already attached to a real
message header, it will appear in that one as well as being registered in this set. If no header is
defined, the field only appears internally.
example: adding a field to a detached list group
my $this = Mail::Message::Head::ListGroup->new(...);
$this->add('List-Id' => 'mailbox');
$msg->addListGroup($this);
$msg->send;
example: adding a field to an attached list group
my $lg = Mail::Message::Head::ListGroup->from($msg);
$lg->add('List-Id' => 'mailbox');
$obj->addFields( [$fieldnames] )
Add some $fieldnames to the set.
$obj->attach($head)
Add a group of fields to a message $head. The fields will be cloned(!) into the header, so that the
field group object can be used again.
example: attaching a list group to a message
my $lg = Mail::Message::Head::ListGroup->new(...);
$lg->attach($msg->head);
$msg->head->addListGroup($lg); # same
$msg->head->addSpamGroup($sg); # also implemented with attach
$obj->delete()
Remove all the header lines which are combined in this fields group, from the header.
$obj->fieldNames()
Return the names of the fields which are used in this group.
$obj->fields()
Return the fields which are defined for this group.
$obj->head()
Returns the header object, which includes these fields.
Accesstotheheader
$obj->software()
Returns the name of the software as is defined in the headers. The may be slightly different from
the return value of type(), but usually not too different.
$obj->type()
Returns an abstract name for the field group; which software is controlling it. "undef" is returned
in case the type is not known. Valid names are group type dependent: see the applicable manual
pages. A list of all types can be retrieved with implementedTypes().
$obj->version()
Returns the version number of the software used to produce the fields. Some kinds of software do
leave such a trace, other cases will return "undef"
Internals
$obj->collectFields( [$name] )
Scan the header for fields which are usually contained in field group with the specified $name. For
mailinglist groups, you can not specify a $name: only one set of headers will be found (all headers
are considered to be produced by exactly one package of mailinglist software).
This method is automatically called when a field group is constructed via from() on an existing
header or message.
Returned are the names of the list header fields found, in scalar context the amount of fields. An
empty list/zero indicates that there was no group to be found.
Please warn the author of MailBox if you see that to few or too many fields are included.
$obj->detected($type, $software, $version)
Sets the values for the field group type, software, and version, prossibly to "undef".
