| libclass-singleton-perl | perl Class::Singleton - Implementation of a "Singleton" class | Mehr ... |
This is the Class::Singleton module. A Singleton describes an object class
that can have only one instance in any system. An example of a Singleton
might be a print spooler or system registry. This module implements a
Singleton class from which other classes can be derived. By itself, the
Class::Singleton module does very little other than manage the instantiation
of a single object. In deriving a class from Class::Singleton, your module
will inherit the Singleton instantiation method and can implement whatever
specific functionality is required.
