public abstract class OperationResponse
extends SessionResponse

Base client operation response.

All operation responses are sent with a result() and the index() (or index) of the state machine at the point at which the operation was evaluated. The version allows clients to ensure state progresses monotonically when switching servers by providing the state machine version in future operation requests.
