Class SummaryClassDescriptionActionListener.Delegating<Response,DelegateResponse>ActionListener.MappedActionListener<Response,MappedResponse>ActionListenerResponseHandler<Response extends TransportResponse>A simple base class for action response listeners, defaulting to using the SAME executor (as its very common on response handlers).Builds and binds the generic action map, all
TransportActions, andActionFilters.Base class for responses to action requests.ActionRunnable<Response>Base class forRunnables that need to callActionListener.onFailure(Exception)in case an uncaught exception or error is thrown while the actual action is run.ActionType<Response extends ActionResponse>A generic action.A base class for the response of a write operation that involves a single docBase class of allDocWriteResponsebuilders.An action listener that allows passing in aCountDownLatchthat will be counted down after onResponse or onFailure is calledNotifyOnceListener<Response>A listener that ensures that only one of onResponse or onFailure is called.Used to keep track of original indices within internal (e.g.RequestValidators<T extends ActionRequest>ResultDeduplicator<T,R>Deduplicator for arbitrary keys and results that can be used to ensure a given action is only executed once at a time for a given request.StepListener<Response>AStepListenerprovides a simple way to write a flow consisting of multiple asynchronous steps without having nested callbacks.Information about task operation failures The class is final due to serialization limitationsA generic proxy that will execute the given action against a specific node. -
