Detailed Description

Convenience method for receiving callbacks from IInformant.

The OnInform() method included here has the method signature that IInformant using when broadcasting notifications back to its client. This interface provides a convenient way to create a target for receiving notifications from the informant, though the informant itself does not require that you use it.

When using this interface, you will need to supply SValue::String("OnInform") for your method on IInformant::RegisterForCallback() and IInformant::RegisterForCreation(), and SValue::String("org.openbinder.services.IInformed") for inspect on IInformant::RegisterForCreation().

Parameters:

[in] information The information value given to IInformant::Inform().

[in] cookie The cookie given when this object was registered.

[in] key The kind of notification being sent.
