Current codebase is fully tested. Next steps : Add Coverage Then go for Json Think about json scheme for custom notification later on
Python Observer pattern using Json
This module contains a Python implementation of the Observer pattern, using json as a format to share information.
See Wikipedia for more information.
Short description of the implementation
Observer :
An observer is uniquey defined by its name. This allows Observable to only notify a given Observer if needed. Observers can subscribe to an Observable and will then receive all future notifications from it. The notifications are sent in json format.
Observable :
An Observable is an entity holding information of interest for other entities. Observers subscribe or unsubscribe to an Observable to get notified any time message is updated.
Description of the package
The Observer pattern does not need any external module to work. Any simple Python installation (>= 2.6) should be enough. To use it, simply copy/paste the module file into your code base and load it in yuor code (import Observer) You are then ready to go !
This package contains several other ressources :
- this README, only used to describe the package and give general information
- testObserver.py, the unit tests of the Observer/Obervable classes.
- exObserver.py, a simple example to show how the Observer pattern can be used.
