virtual void onImpliedBookUpdated ( const ImpliedBook &  book, const ChannelId &  channelId  )

pure virtual

Is called when the implied book is updated.

In compare to the change reported through 'ImpliedBookChangeListener' interface, update represents a complex operation and usually consists of multiple changes. Also, books reported via 'ImpliedBookUpdateListener' interface are always in a valid state, whereas atomic change may invalidate book until subsequent change.
