6 User::Identity::Item - general base class for User::Identity
7
9 User::Identity::Item is extended by
10 Mail::Identity
11 User::Identity
12 User::Identity::Archive
13 User::Identity::Collection
14 User::Identity::Location
15 User::Identity::System
16
19 The "User::Identity::Item" base class is extended into useful modules:
20 it has no use by its own.
21
23 Constructors
24 User::Identity::Item->new( [$name], %options )
25 -Option --Default
26 description undef
27 name <required>
28 parent undef
29
30 description => STRING
31 Free format description on the collected item.
32
33 name => STRING
34 A simple name for this item. Try to give a useful name in the
35 context of the item time. Each time when you lookup items, you
36 need to specify this name, so it should be unique and not to hard
37 to handle in your program. For instance, when a person is
38 addressed, you usually will give him/her this a nickname.
39
40 parent => OBJECT
41 The encapsulating object: the object which collects this one.
42
43 Attributes
44 $obj->description()
45 Free format description on this item. Please do not add any
46 significance to the content of this field: if you are in need for
47 an extra attribute, please contact the author of the module to
48 implement it, or extend the object to suit your needs.
49
50 $obj->name( [$newname] )
51 The name of this item. Names are unique within a collection... a
52 second object with the same name within any collection will destroy
53 the already existing object with that name.
54
55 Changing the name of an item is quite dangerous. You probably want
56 to call User::Identity::Collection::renameRole() instead.
57
58 Collections
59 $obj->add($collection, $role)
60 The $role is added to the $collection. The $collection is the name
61 of a collection, which will be created automatically with
62 addCollection() if needed. The $collection can also be specified
63 as existing collection object.
64
65 The $role is anything what is acceptable to
66 User::Identity::Collection::addRole() of the collection at hand,
67 and is returned. $role typically is a list of parameters for one
68 role, or a reference to an array containing these values.
69
70 example:
71
72 my $ui = User::Identity->new(...);
73 my $home = $ui->add(location => [home => street => '27 Roadstreet', ...] );
74 my $work = $ui->add(location => work, tel => '+31-2231-342-13', ... );
75
76 my $travel = User::Identity::Location->new(travel => ...);
77 $ui->add(location => $travel);
78
79 my $system = User::Identity::Collection::System->new(...);
80 $ui->add($system => 'localhost');
81
82 $obj->addCollection( $object | <[$type], %options> )
83 Add a new collection of roles to an item. This can be achieved in
84 two ways: either create an User::Identity::Collection $object
85 yourself and then pass that to this method, or supply all the
86 %options needed to create such an object and it will be created for
87 you. The object which is added is returned, and can be used for
88 many methods directly.
89
90 For %options, see the specific type of collection. Additional
91 options are listed below.
92
93 -Option--Default
94 type <required>
95
96 type => STRING|CLASS
97 The nickname of a collection class or the CLASS name itself of
98 the object to be created. Required if an object has to be
99 created. Predefined type nicknames are "email", "system", and
100 "location".
101
102 example:
103
104 my $me = User::Identity->new(...);
105 my $locs = User::Identity::Collection::Locations->new();
106 $me->addCollection($locs);
107
108 my $email = $me->addCollection(type => 'email');
109 my $email = $me->addCollection('email');
110
111 $obj->collection($name)
112 In scalar context the collection object with the $name is returned.
113 In list context, all the roles within the collection are returned.
114
115 example:
116
117 my @roles = $me->collection('email'); # list of collected items
118 my @roles = $me->collection('email')->roles; # same of collected items
119 my $coll = $me->collection('email'); # a User::Identity::Collection
120
121 $obj->parent( [$parent] )
122 Returns the parent of an Item (the enclosing item). This may
123 return "undef" if the object is stand-alone.
124
125 $obj->removeCollection($object|$name)
126 $obj->type()
127 User::Identity::Item->type()
128 Returns a nice symbolic name for the type.
129
130 $obj->user()
131 Go from this object to its parent, to its parent, and so on, until
132 a User::Identity is found or the top of the object tree has been
133 reached.
134
135 example:
136
137 print $email->user->fullName;
138
139 Searching
140 $obj->find($collection, $role)
141 Returns the object with the specified $role within the named
142 collection. The collection can be specified as name or object.
143
144 example:
145
146 my $role = $me->find(location => 'work'); # one location
147 my $role = $me->collection('location')->find('work'); # same
148
149 my $email = $me->addCollection('email');
150 $me->find($email => 'work');
151 $email->find('work'); # same
152
154 Error: $object is not a collection.
155 The first argument is an object, but not of a class which extends
156 User::Identity::Collection.
157
158 Error: Cannot load collection module for $type ($class).
159 Either the specified $type does not exist, or that module named
160 $class returns compilation errors. If the type as specified in the
161 warning is not the name of a package, you specified a nickname
162 which was not defined. Maybe you forgot the 'require' the package
163 which defines the nickname.
164
165 Error: Creation of a collection via $class failed.
166 The $class did compile, but it was not possible to create an object
167 of that class using the options you specified.
168
169 Error: Don't know what type of collection you want to add.
170 If you add a collection, it must either by a collection object or a
171 list of options which can be used to create a collection object.
172 In the latter case, the type of collection must be specified.
173
174 Error: Each item requires a name
175 You have to specify a name for each item. These names need to be
176 unique within one collection, but feel free to give the same name
177 to an e-mail address and a location.
178
179 Warning: No collection $name
180 The collection with $name does not exist and can not be created.
181
182 Warning: Unknown option $name for a $class
183 One used option is not defined. Check the manual page of the class
184 to see which options are accepted.
185
186 Warning: Unknown options @names for a $class
187 More than one option is not defined.
