BeanBlockContribution	A contribution to the BeanBlockSource service, defining a page name and block id (within the page) that can edit or display a particular type of property.
ComponentEventRequestParameters	Encapsulates all the information that may be provided in a component event request URL.
ComponentLibraryInfo	Class that encapsulates information about a component library, going beyond what a library mapping provides.
ComponentLibraryInfo.DefaultSourceUrlResolver	Default ComponentLibraryInfo.SourceUrlResolver implementation.
DefaultObjectRenderer	Default object renderer as a catch all for class Object.
DelegatingRequest	Class that wraps an Request, delegating all its methods.
DisplayBlockContribution	Contribution to BeanBlockSource identifying a block that is used to display a property.
EditBlockContribution	Contribution to BeanBlockSource identifying a block that is used to edit a property.
GenericsResolver.Provider	Convenience class for getting a GenericsResolver instance.
HttpError	An event handler method may return an instance of this class to send an error response to the client.
InitializeActivePageName	Filter contributed into the ComponentRequestHandler pipeline to set the activePageName property.
LibraryMapping	Used to configure the ComponentClassResolver, to allow it to map library names to library root packages (the application namespace is a special case of this).
