Interface IAsyncCallback<T>

All Known Subinterfaces:

IAsyncCallbackWithFailure<T>

All Known Implementing Classes:

AbstractPaxosCallback, AbstractWriteResponseHandler, AnticompactionTask.AnticompactionCallback, AsyncOneResponse, AsyncRepairCallback, DatacenterSyncWriteResponseHandler, DatacenterWriteResponseHandler, PrepareCallback, ProposeCallback, ReadCallback, TruncateResponseHandler, WriteResponseHandler

public interface IAsyncCallback<T>

implementors of IAsyncCallback need to make sure that any public methods are threadsafe with respect to response() being called from the message service. In particular, if any shared state is referenced, making response alone synchronized will not suffice.
