User::Identity::CollecUser(Contributed Perl DocUser::Identity::Collection(3pm)

       User::Identity::Collection - base class for collecting roles of a user

          is an User::Identity::Item

        User::Identity::Collection is extended by

        use User::Identity;
        use User::Identity::Collection;
        my $me    = User::Identity->new(...);
        my $set   = User::Identity::Collection::Emails->new(...);

        # Simpler
        use User::Identity;
        my $me    = User::Identity->new(...);
        my $set   = $me->addCollection(type => 'email', ...)
        my $set   = $me->addCollection('email', ...)

        my @roles = $me->collection('email');  # list of collected items

        my $coll  = $me->collection('email');  # a User::Identity::Collection
        my @roles = $coll->roles;
        my @roles = @$coll;                    # same, by overloading

        my $role  = $me->collection('email')->find($coderef);
        my $role  = $me->collection('location')->find('work');
        my $role  = $me->find(location => 'work');

       The "User::Identity::Collection" object maintains a set user related
       objects.  It helps selecting these objects, which is partially common
       to all collections (for instance, each object has a name so you can
       search on names), and sometimes specific to the extension of this col-

       Currently imlemented extensions are

       * people is a collection of users
       * whereabouts are locations
       * a mailinglist is a
           collection of email addresses

       * a network contains
           groups of systems

       overload: @{}

           When the reference to a collection object is used as array-refer-
           ence, it will be shown as list of roles.


            my $locations = $ui->collection('location');
            foreach my $loc (@$location) ...
            print $location->[0];

       overload: stringification

           Returns the name of the collection and a sorted list of defined


            print "$collection\n";  #   location: home, work


       User::Identity::Collection->new([NAME], OPTIONS)

        Option     --Defined in     --Default
        description  User::Identity::Item  undef
        item_type                     <required>
        name         User::Identity::Item  <required>
        parent       User::Identity::Item  undef
        roles                         undef

           . description => STRING

           . item_type => CLASS

               The CLASS which is used to store the information for each of
               the maintained objects within this collection.

           . name => STRING

           . parent => OBJECT

           . roles => ROLE|ARRAY

               Immediately add some roles to this collection.  In case of an
               ARRAY, each element of the array is passed separately to add-
               Role(). So, you may end-up with an ARRAY of arrays each group-
               ing a set of options to create a role.

           Returns the type of the items collected.


           See "Attributes" in User::Identity::Item


           Returns all defined roles within this collection.  Be warned: the
           rules are returned in random (hash) order.

       Maintaining roles

       $obj->addRole(ROLE| ( [NAME],OPTIONS ) | ARRAY-OF-OPTIONS)

           Adds a new role to this collection.  ROLE is an object of the right
           type (depends on the extension of this module which type that is)
           or a list of OPTIONS which are used to create such role.  The
           options can also be passed as reference to an array.  The added
           role is returned.


            my $uicl = User::Identity::Collection::Locations->new;

            my $uil  = User::Identity::Location->new(home => ...);

            $uicl->addRole( home => address => 'street 32' );
            $uicl->addRole( [home => address => 'street 32'] );


            $ui      = User::Identity;
            $ui->add(location => 'home', address => 'street 32' );
            $ui->add(location => [ 'home', address => 'street 32' ] );


           The deleted role is returned (if it existed).

       $obj->renameRole(ROLE|OLDNAME, NEWNAME)

           Give the role a different name, and move it in the collection.


           Returns the roles sorted by name, alphabetically and case-sensi-



           Find the object with the specified NAME in this collection.  With
           "undef", a randomly selected role is returned.

           When a code reference is specified, all collected roles are scanned
           one after the other (in unknown order).  For each role,

            CODE->($object, $collection)

           is called.  When the CODE returns true, the role is selected.  In
           list context, all selected roles are returned.  In scalar context,
           the first match is returned and the scan is aborted immediately.


            my $emails = $ui->collection('emails');

            sub find_work($$) {
               my ($mail, $emails) = @_;
               $mail->location->name eq 'work';
            my @at_work = $emails->find(\&find_work);
            my @at_work = $ui->find(location => \&find_work);
            my $any     = $ui->find(location => undef );

       Error: $object is not a collection.

           The first argument is an object, but not of a class which extends

       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.

       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.

       Error: Cannot rename $name into $newname: already exists

       Error: Cannot rename $name into $newname: doesn't exist

       Error: Creation of a collection via $class failed.

           The $class did compile, but it was not possible to create an object
           of that class using the options you specified.

       Error: Don't know what type of collection you want to add.

           If you add a collection, it must either by a collection object or a
           list of options which can be used to create a collection object.
           In the latter case, the type of collection must be specified.

       Warning: No collection $name

           The collection with $name does not exist and can not be created.

       Error: Wrong type of role for $collection: requires a $expect but got a

           Each $collection groups sets of roles of one specific type
           ($expect).  You cannot add objects of a different $type.
