METHODS

Constructors

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
  description  User::Identity::Item  undef
  hostname                      'localhost'
  location                      undef
  name         User::Identity::Item  <required>
  os                            undef
  parent       User::Identity::Item  undef

. description => STRING

. hostname => DOMAIN

The hostname of the described system. It is prefered to use full system names, not abbreviations. For instance, you can better use "www.tux.aq" than "www" to avoid confusion.

. location => NICKNAME|OBJECT

The NICKNAME of a location which is defined for the same user. You can also specify a User::Identity::Location OBJECT.

. name => STRING
. os => STRING

The name of the operating system which is run on the server. It is adviced to use the names as used by Perl's $^O variable. See the perlvar man-page for this variable, and perlport for the possible values.

. parent => OBJECT
. password => STRING

The password to be used to login. This password must be un-encoded: directly usable. Be warned that storing un-encoded passwords is a high security list.

. username => STRING

The username to be used to login to this host.

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.

Warning: No collection $name

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