User::Identity::System - physical system of a person

 User::Identity::System
   is a User::Identity::Item

 use User::Identity;
 use User::Identity::System;
 my $me   = User::Identity->new(...);
 my $server = User::Identity::System->new(...);
 $me->add(system => $server);

 # Simpler

 use User::Identity;
 my $me   = User::Identity->new(...);
 my $addr = $me->add(system => ...);

The CWUser::Identity::System object contains the description of the user's presence on a system. The systems are collected by an User::Identity::Collection::Systems object.

Nearly all methods can return undef.

User::Identity::System->new([NAME], OPTIONS) Create a new system. You can specify a name as first argument, or in the OPTION list. Without a specific name, the organization is used as name.

 Option       Defined in       Default

 hostname                      C<'localhost'>

Error: CW$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 CW$type ($class).

Either the specified CW$type does not exist, or that module named CW$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 CW$class failed.

The CW$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 CW$name

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