In deriving a class from Class::Singleton, your\nmodule will inherit the Singleton instantiation method and can\nimplement whatever specific functionality is required.\n\nFor a description and discussion of the Singleton class, see\n\"Design Patterns\", Gamma et al, Addison-Wesley, 1995, ISBN 0-\n201-63361-2.\n","description_source":null,"description_unresolved":[],"package_architecture":"*","stem":"p5-Class-Singleton","readme":null,"dependencies":[],"reverse_dependencies":{"count":6,"url":"/packages/data/c4/c4d89855312ae9b0de975f2a6404655bb6aa176aefd4701a5729ec92b8cf1a78.json"},"categories":["devel","perl5"],"flavors":[],"only_for_architectures":[],"not_for_architectures":[]}}
