Class CCHFTopParent

class CCHFTopParent : public CCHFSession, public MCHFParent, public MCHFDiscoveryService, public MCHFEventMappingService;

Description

Base class for the one and only application's CHF Session object.

The class provides the API for the services that must be provided by the derived class for the Content Handling Framework to function. It holds a collection of services, including the discovery of private - client supplied - and plug-in components such as data suppliers and content handlers and event mapping services.

The derived class must call the BaseConstructL() as part of its construction sequence, preferably from its ConstructL().

Derivation

• MCHFEventMappingService - Pure virtual base class API for mapping raw events to CHF abstract events
• MCHFDiscoveryService - Base interface used for the CHF discovery service
• MCHFParent - Interface for parents of content handlers

• CBase - Base class for all classes to be instantiated on the heap

• CCHFSession - CHF framework session

• CCHFTopParent - Base class for the one and only application's CHF Session object
