Interface Callback

public interface Callback

Definition of the callback interface for the statistics API. It is a common use case to need a reference to the Handle (e.g. Value or Counter) which a callback is related to. Since everything in a Handle since 5.1.4 is fully initialized from the constructor, it became cumbersome to use Runnable for the callback and this interface came into use.

Since:

5.1.4
