ActionFactory<A extends Action>	An action factory is an object which knows how to create Action:s.
ErrorHandler<A extends Action>	Error handlers are created by the factory for each request/use of an extension point.
ErrorHandlerFactory<A extends Action>	Error handler factories are responsible for creating error handlers.
Extension<A extends Action>	Represents a concrete implementation of an extension to an extension point.
ExtensionPoint<A extends Action>	An extension point is a place, defined by a client application, that can be extended.
ExtensionsFilter	Allows extensions and extension points to be enabled/disabled and sorted externally.
Renderer<A extends Action>	A renderer is an object that knows how to render an action in the client interface.
RendererFactory<A extends Action>	A renderer factory is a factory that can create Renderer objects.

Class Summary

AboutBean	An implementation of the About interface, which complements all getter methods with setter methods.
ActionIterator<A extends Action>	Iterator for iterating over all actions that will be created by extensions after a call to Registry.useExtensions(ClientContext, ExtensionsFilter, String...).
ClientContext	Keeps information about the current context in the client application that extensions can use to decide what actions to generate.
DefaultFilter	A default filter implementation that enables all extensions and extension points and sorts the extensions based on the Extension.getIndex() values.
ExtensionBean<A extends Action>	A bean-like implementation of the Extension interface.
ExtensionContext<A extends Action>	Invokation context for an extension.
ExtensionPointBean<A extends Action>	A bean-like implementation of the ExtensionPoint interface.
ExtensionPointContext<A extends Action>	Invokation context for an extension point.
ExtensionsInvoker<A extends Action>	Object of this class handles a single invokation of the extensions for one or several extension points.
InvokationContext<A extends Action>	Keeps contextual information about a single invokation of extensions.
LoggingErrorHandlerFactory	Exception handler factory implementation that logs error messages using the default logging mechanism.
Registry	A registry for keeping track of extensions points and installed extensions.
Registry.AttributeKey	Identifies attribute.
Registry.RegisteredAbout
Registry.RegisteredExtension<A extends Action>	Internal representation of an extension.
Registry.RegisteredExtensionPoint<A extends Action>	Internal representation of an extension point.
RethrowErrorHandlerFactory	Extension to the logging error handler factory that create error handlers that re-throw the original exception.
SingleExtensionFilter	A filter implementation that enables a single extension and disables all other.
