pyutilib.component.core 4.3

The PyUtilib Component Architecture.

Overview

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:

Trac	PyUtilib
Interface	Interface
ExtensionPoint	ExtensionPoint
Component	SingletonPlugin
ComponentManager	PluginEnvironment

See The PyUtilib Component Architecture Reference Manual for a detailed description of PyUtilib components and examples of their use.
