The PyUtilib Component Architecture.
This Python package provides a modular component framework, which consists of the following core classes:
|Interface:||Subclasses of this class declare component interfaces that are registered in the framework|
|ExtensionPoint:||A class used to declare extension points, which can access components with a particular interface|
|Plugin:||Subclasses of this class declare plugins, which can be used to provide services within this component framework.|
|SingletonPlugin:||Subclasses of this class declare singleton plugins, for which a single instance can be declared.|
|PluginEnvironment:||A class that maintains the registries for interfaces, extension points and components.|
|PluginGlobals:||A class that maintains global data concerning the set of environments that are currently being used.|
|PluginError:||The exception class that is raised when errors arise in this framework.|
The outline of this framework is adapted from Trac (see the trac.core module). This framework generalizes the Trac by supporting multi-environment management of components, as well as non-singleton plugins. For those familiar with Trac, the following classes roughly correspond with each other:
