CLiwServiceIfBase Class Reference
| class CLiwServiceIfBase : public CBase |
This is the base service interface to access providers that offer base services.
This interface needs to be implemented by all the LIW providers. Base service providers should inherit from this class directly. Menu service providers should inherit from CLiwServiceIfMenu.

InitialiseL(MLiwNotifyCallback &, const RCriteriaArray &)
Called by the LIW framework to initialise provider with necessary information from the Service Handler. This method is called when the consumer makes the attach operation.
Parameters
| MLiwNotifyCallback & aFrameworkCallback | Framework provided callback for provider to send events to framework. |
| const RCriteriaArray & aInterest | List of criteria items which invoked the provider. |
