| Hans-Günter@24185 | 1 This is the Class::Singleton module. |
| Hans-Günter@24185 | 2 A Singleton describes an object class that can have only one |
| Hans-Günter@24185 | 3 instance in any system. |
| Hans-Günter@24185 | 4 An example of a Singleton might be a print spooler or system |
| Hans-Günter@24185 | 5 registry. |
| Hans-Günter@24185 | 6 This module implements a Singleton class from which other |
| Hans-Günter@24185 | 7 classes can be derived. By itself, the Class::Singleton module |
| Hans-Günter@24185 | 8 does very little other than manage the instantiation of a |
| Hans-Günter@24185 | 9 single object. In deriving a class from Class::Singleton, |
| Hans-Günter@24185 | 10 your module will inherit the Singleton instantiation method and |
| Hans-Günter@24185 | 11 can implement whatever specific functionality is required. |
