All Known Implementing Classes:

DefaultRpcResponse

public interface RpcResponse
extends Response, Future<Object>, CompletionStage<Object>

An RPC Response. It is a CompletionStage whose result signifies the return value of an RPC call.

Method Summary

Modifier and Type	Method and Description
Throwable	cause() Returns the cause of the failure if this RpcResponse completed exceptionally.
default CompletableFuture<?>	completionFuture() Returns a CompletableFuture which completes when this RpcResponse completes.
static RpcResponse	from(CompletionStage<?> stage) Creates a new RpcResponse that is completed successfully or exceptionally based on the completion of the specified CompletionStage.
Object	getNow(Object valueIfAbsent) Returns the specified valueIfAbsent when not complete, or returns the result value or throws an exception when complete.
boolean	isCompletedExceptionally() Returns true if this RpcResponse completed exceptionally.
Object	join() Returns the result value if completed successfully or throws an unchecked exception if completed exceptionally.
static RpcResponse	of(Object value) Creates a new successfully complete RpcResponse.
static RpcResponse	ofFailure(Throwable cause) Creates a new exceptionally complete RpcResponse.
