HandleProtocolConnectionHostEvent(const MXIMPProtocolConnectionHost &, const MXIMPBase &)

void	HandleProtocolConnectionHostEvent	(	const MXIMPProtocolConnectionHost &	aHost,
			const MXIMPBase &	aEvent
		)	[pure virtual]

Event callback.

Events are delivered as MXIMPBase typed objects. Protocol adaptation can use MXIMPBase::InterfaceId() to identify the real event interface type. Observer can use cast methods provided in MXimpFw...Event interfaces to cast to real event interface.

Parameters

const MXIMPProtocolConnectionHost & aHost	XIMP host object from where this event is coming. Provided as reference for protocol adaptation, so observer can distinguish events coming from different hosts if listened in single observer.
const MXIMPBase & aEvent	The event object. Client can use MXIMPBase::InterfaceId() to determine correct event type and interface cast methods from MXimpFw...Event interfaces to cast object to real event interface.

aInterfaceId

)

[inline, virtual]

Extension point for this observer interface.

Returns an pointer to MXIMPProtocolConnectionHostObserver extension interface or NULL if the concrete observer implementation doesn't support requested extension.

Parameters

TInt32 aInterfaceId

Interface ID identifying the requested extension interface.
