DESCRIPTION

31       Dancer::Object::Singleton is meant to be used instead of
32       Dancer::Object, if you want your object to be a singleton, that is, a
33       class that has only one instance in the application.
34
35       It provides you with attributes and an initializer.
36

METHODS

38   instance
39       Returns the instance of the singleton. The instance is created only
40       when needed. The creation will call the "init()" method, which you
41       should implement.
42
43   init
44       Exists but does nothing. This is so you won't have to write an
45       initializer if you don't want to. init receives the instance as
46       argument.
47
48   get_attributes
49       Get the attributes of the specific class.
50
51   attributes
52       Generates attributes for whatever object is extending Dancer::Object
53       and saves them in an internal hashref so they can be later fetched
54       using "get_attributes".
