SYNOPSIS
  my $g = Mail::Message::Field::AddrGroup->new(name => 'name');

DESCRIPTION
An address group collects a set of e-mail addresses (in this case they are Mail::Message::Field::Address objects).

Extends "DESCRIPTION" in User::Identity::Collection::Emails.

OVERLOADED
Extends "OVERLOADED" in User::Identity::Collection::Emails.

overload: "" stringification
    Returns the string() value.

overload: '""' stringification

overload: '@{}' array dereference
    Inherited, see "OVERLOADED" in User::Identity::Collection

METHODS
Extends "METHODS" in User::Identity::Collection::Emails.

$obj->string()
    Returns the address group as string. When no name is specified, it will only be a comma separated list of addresses. With a name, the groups name will be prepended and a semi-colon appended. When no addresses where included and there is no name, then "undef" is returned.

  Constructors
Extends "Constructors" in User::Identity::Collection::Emails.

$obj->coerce($object)
    Coerce an $object into a Mail::Message::Field::AddrGroup. Currently, you can only coerce User::Identity::Collection::Emails (which is the base class for this one) into this one.

$class->new( [$name], %options )
    Inherited, see "Constructors" in User::Identity::Collection::Emails

  Collections

  Maintaining roles

  Addresses

$obj->addAddress(STRING|$address|%options)
    Add one e-mail address to the list which is maintained in the group. This is a wrapper around addRole() adding flexibility on how addresses are specified. An $address can be anything which is acceptable for Mail::Message::Field::Address::coerce() or a list of options which will create such an object.

    » example: of adding an address to an address group

      my @data = (full_name => "Myself", address => 'me@tux.org');
      $group->addAddress(@data);

      my $addr = Mail::Message::Field::Address->new(@data);
      $group->addAddress(@data);

      my $ma = Mail::Address->new(...);
      $group->addAddress($ma);

$obj->addresses()
    Returns all addresses defined in this group. The addresses will be ordered alphabetically to make automated testing possible: roles are stored in a hash, so have an unpredictable order by default.

    » example: getting all addresses from a group

      my @addrs = $group->addresses;
      my @addrs = map $_->address, $self->roles; #same

  Error handling

DIAGNOSTICS

Error: cannot coerce a $type into a $class.
    Cast by coerce()

Error: cannot create a $type to add this to my collection.
    Some options are specified to create a $type object, which is native to this collection. However, for some reason this failed. Cast by addRole()

Error: cannot load collection module for $type ($class): $@
    Either the specified $type does not exist, or that module named $class returns compilation errors. If the type as specified in the warning is not the name of a package, you specified a nickname which was not defined. Maybe you forgot the 'require' the package which defines the nickname. Cast by addCollection()

Error: cannot rename $from into $to: already exists.
    Cast by renameRole()

Error: cannot rename $from into $to: doesn't exist.
    Cast by renameRole()

Error: invalid collection $name.
    The collection with $name does not exist and can not be created. Cast by add()

Error: this $object is not a collection.
    Cast by addCollection()

Error: wrong type of role for $collection: requires a $expect but got a $type.
    Each $collection groups sets of roles of one specific type ($expect). You cannot add objects of a different $type. Cast by addRole()
