NAME
User::Identity::Item - general base class for User::Identity
INHERITANCE
User::Identity::Item is extended by
Mail::Identity
User::Identity
User::Identity::Archive
User::Identity::Collection
User::Identity::Location
User::Identity::System
SYNOPSIS
DESCRIPTION
The "User::Identity::Item" base class is extended into useful modules: it has no use by
its own.
METHODS
Constructors
User::Identity::Item->new( [NAME], OPTIONS )
-Option --Default
description undef
name <required>
parent undef
description => STRING
Free format description on the collected item.
name => STRING
A simple name for this item. Try to give a useful name in the context of the item
time. Each time when you lookup items, you need to specify this name, so it should
be unique and not to hard to handle in your program. For instance, when a person is
addressed, you usually will give him/her this a nickname.
parent => OBJECT
The encapsulating object: the object which collects this one.
Attributes
$obj->description()
Free format description on this item. Please do not add any significance to the
content of this field: if you are in need for an extra attribute, please contact the
author of the module to implement it, or extend the object to suit your needs.
$obj->name( [NEWNAME] )
The name of this item. Names are unique within a collection... a second object with
the same name within any collection will destroy the already existing object with that
name.
Changing the name of an item is quite dangerous. You probably want to call
User::Identity::Collection::renameRole() instead.
Collections
$obj->add(COLLECTION, ROLE)
The ROLE is added to the COLLECTION. The COLLECTION is the name of a collection,
which will be created automatically with addCollection() if needed. The COLLECTION
can also be specified as existing collection object.
The ROLE is anything what is acceptable to User::Identity::Collection::addRole() of
the collection at hand, and is returned. ROLE typically is a list of parameters for
one role, or a reference to an array containing these values.
example:
my $ui = User::Identity->new(...);
my $home = $ui->add(location => [home => street => '27 Roadstreet', ...] );
my $work = $ui->add(location => work, tel => '+31-2231-342-13', ... );
my $travel = User::Identity::Location->new(travel => ...);
$ui->add(location => $travel);
my $system = User::Identity::Collection::System->new(...);
$ui->add($system => 'localhost');
$obj->addCollection(OBJECT | ([TYPE], OPTIONS))
Add a new collection of roles to an item. This can be achieved in two ways: either
create an User::Identity::Collection OBJECT yourself and then pass that to this
method, or supply all the OPTIONS needed to create such an object and it will be
created for you. The object which is added is returned, and can be used for many
methods directly.
For OPTIONS, see the specific type of collection. Additional options are listed
below.
-Option--Default
type <required>
type => STRING|CLASS
The nickname of a collection class or the CLASS name itself of the object to be
created. Required if an object has to be created. Predefined type nicknames are
"email", "system", and "location".
example:
my $me = User::Identity->new(...);
my $locs = User::Identity::Collection::Locations->new();
$me->addCollection($locs);
my $email = $me->addCollection(type => 'email');
my $email = $me->addCollection('email');
$obj->collection(NAME)
In scalar context the collection object with the NAME is returned. In list context,
all the roles within the collection are returned.
example:
my @roles = $me->collection('email'); # list of collected items
my @roles = $me->collection('email')->roles; # same of collected items
my $coll = $me->collection('email'); # a User::Identity::Collection
$obj->find(COLLECTION, ROLE)
Returns the object with the specified ROLE within the named collection. The
collection can be specified as name or object.
example:
my $role = $me->find(location => 'work'); # one location
my $role = $me->collection('location')->find('work'); # same
my $email = $me->addCollection('email');
$me->find($email => 'work');
$email->find('work'); # same
$obj->parent( [PARENT] )
Returns the parent of an Item (the enclosing item). This may return "undef" if the
object is stand-alone.
$obj->removeCollection(OBJECT|NAME)
$obj->type()
User::Identity::Item->type()
Returns a nice symbolic name for the type.
$obj->user()
Go from this object to its parent, to its parent, and so on, until a User::Identity is
found or the top of the object tree has been reached.
example:
print $email->user->fullName;
DIAGNOSTICS
Error: $object is not a collection.
The first argument is an object, but not of a class which extends
User::Identity::Collection.
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: 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.
Error: Each item requires a name
You have to specify a name for each item. These names need to be unique within one
collection, but feel free to give the same name to an e-mail address and a location.
Warning: No collection $name
The collection with $name does not exist and can not be created.
Warning: Unknown option $name for a $class
One used option is not defined. Check the manual page of the class to see which
options are accepted.
Warning: Unknown options @names for a $class
More than one option is not defined.
