org.apache.dubbo.rpc使用的org.apache.dubbo.rpc中的类

类和说明
AdaptiveMetrics adaptive Metrics statistics.
AppResponse AsyncRpcResult is introduced in 3.0.0 to replace RpcResult, and RpcResult is replaced with AppResponse: AsyncRpcResult is the object that is actually passed in the call chain AppResponse only simply represents the business result The relationship between them can be described as follow, an abstraction of the definition of AsyncRpcResult: Public class AsyncRpcResult implements CompletionStage { ...... } AsyncRpcResult is a future representing an unfinished RPC call, while AppResponse is the actual return type of this call.
AsyncContext AsyncContext works like javax.servlet.AsyncContext in the Servlet 3.0.
AsyncRpcResult This class represents an unfinished RPC call, it will hold some context information for this call, for example RpcContext and Invocation, so that when the call finishes and the result returns, it can guarantee all the contexts being recovered as the same as when the call was made before any callback is invoked.
BaseFilter
BaseFilter.Listener This callback listener applies to both synchronous and asynchronous calls, please put logics that need to be executed on return of rpc result in onResponse or onError respectively based on it is normal return or exception return.
CancellationContext
CancellationListener A listener notified on context cancellation.
ExecutableListener
Exporter Exporter.
Filter Extension for intercepting the invocation for both service provider and consumer, furthermore, most of functions in dubbo are implemented base on the same mechanism.
FutureContext Used for async call scenario.
Invocation Invocation.
InvokeMode
Invoker Invoker.
ProtocolServer Distinct from RemotingServer, each protocol holds one or more ProtocolServers(the number usually decides by port numbers), while each ProtocolServer holds zero or one RemotingServer.
Result (API, Prototype, NonThreadSafe) An RPC Result.
RpcContext Thread local context.
RpcContext.RestoreServiceContext
RpcContextAttachment
RpcException RPC Exception.
RpcInvocation RPC Invocation.
RpcServiceContext
RpcStatus URL statistics.
