User::Identity(3pm)   User Contributed Perl Documentation  User::Identity(3pm)

       User::Identity - maintains info about a physical person

          is an User::Identity::Item

        use User::Identity;
        my $me = User::Identity->new
         ( 'john'
         , firstname => 'John'
         , surname   => 'Doe'
        print $me->fullName  # prints "John Doe"
        print $me;           # same

       The "User::Identity" object is created to maintain a set of informa-
       tional objects which are related to one user.  The "User::Identity"
       module tries to be smart providing defaults, conversions and often
       required combinations.

       The identities are not implementing any kind of storage, and can there-
       fore be created by any simple or complex Perl program.  This way, it is
       more flexible than an XML file to store the data.  For instance, you
       can decide to store the data with Data::Dumper, Storable, DBI, Address-
       Book or whatever.  Extension to simplify this task are still to be

       If you need more kinds of user information, then please contact the
       module author.


           When an "User::Identity" is used as string, it is automatically
           translated into the fullName() of the user involved.


            my $me = User::Identity->new(...)
            print $me;          # same as  print $me->fullName
            print "I am $me\n"; # also stringification


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

           Create a new user identity, which will contain all data related to
           a single physical human being.  Most user data can only be speci-
           fied at object construction, because they should never change.  A
           NAME may be specified as first argument, but also as option, one
           way or the other is required.

           Calcuted from the datge of birth to the current moment, as integer.
           On the birthday, the number is incremented already.


           Returns the date in standardized format: YYYYMMDD, easy to sort and
           select.  This may return "undef", even if the dateOfBirth() con-
           tains a value, simply because the format is not understood. Month
           or day may contain '00' to indicate that those values are not


           The user's prefered character set, which defaults to the value of
           LC_CTYPE environment variable.


           The courtesy is used to address people in a very formal way.  Val-
           ues are like "Mr.", "Mrs.", "Sir", "Frau", "Heer", "de heer",
           "mevrouw".  This often provides a way to find the gender of someone


           Returns the date of birth, as specified during instantiation.


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


           Returns the first name of the user.  If it is not defined explic-
           itly, it is derived from the nickname, and than capitalized if


           Returns a formal name for the user.  If not defined as instantia-
           tion parameter (see new()), it is constructed from other available
           information, which may result in an incorrect or an incomplete
           name.  The result is built from "courtesy initials prefix surname


           If this is not specified as value during object construction, it is
           guessed based on other known values like "firstname prefix sur-
           name".  If a surname is provided without firstname, the nickname is
           taken as firstname.  When a firstname is provided without surname,
           the nickname is taken as surname.  If both are not provided, then
           the nickname is used as fullname.


           Returns the specified gender of the person, as specified during
           instantiation, which could be like 'Male', 'm', 'homme', 'man'.
           There is no smart behavior on this: the exact specified value is
           returned. Methods isMale(), isFemale(), and courtesy() are smart.


           The initials, which may be derived from the first letters of the

           Returns true if we are sure that the user is male.  This is speci-
           fied as gender at instantiation, or derived from the courtesy
           value.  Methods isMale and isFemale are not complementatory: they
           can both return false for the same user, in which case the gender
           is undertermined.


           Can contain a list or a single language name, as defined by the RFC
           Examples are 'en', 'en-GB', 'nl-BE'.  The default language  is 'en'


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


           Returns the user's nickname, which could be used as username,
           e-mail alias, or such.  When no nickname was explicitly specified,
           the name is used.


           The words which are between the firstname (or initials) and the


           Returns the surname of person, or "undef" if that is not known.


           The titles, degrees in education or of other kind.  If these are
           complex, you may need to specify the formal name of the users as
           well, because smart formatting probably failes.

       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.

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