AsyncContextImpl

public AsyncContextImpl()

方法详细资料

write

public void write(Object value)

从接口复制的说明: AsyncContext

write value and complete the async context.

指定者:

write 在接口中 AsyncContext

参数:

value - invoke result

isAsyncStarted

public boolean isAsyncStarted()

指定者:

isAsyncStarted 在接口中 AsyncContext

返回:

true if the async context is started

stop

public boolean stop()

从接口复制的说明: AsyncContext

change the context state to stop

指定者:

stop 在接口中 AsyncContext

start

public void start()

从接口复制的说明: AsyncContext

change the context state to start

指定者:

start 在接口中 AsyncContext

signalContextSwitch

public void signalContextSwitch()

从接口复制的说明: AsyncContext

Signal RpcContext switch. Use this method to switch RpcContext from a Dubbo thread to a new thread created by the user. Note that you should use it in a new thread like this: public class AsyncServiceImpl implements AsyncService { public String sayHello(String name) { final AsyncContext asyncContext = RpcContext.startAsync(); new Thread(() -> { // right place to use this method asyncContext.signalContextSwitch(); try { Thread.sleep(500); } catch (InterruptedException e) { e.printStackTrace(); } asyncContext.write("Hello " + name + ", response from provider."); }).start(); return null; } }

指定者:

signalContextSwitch 在接口中 AsyncContext

resetContext

public void resetContext()

从接口复制的说明: AsyncContext

Reset Context is not necessary. Only reset context after result was write back if it is necessary. public class AsyncServiceImpl implements AsyncService { public String sayHello(String name) { final AsyncContext asyncContext = RpcContext.startAsync(); new Thread(() -> {

// the right place to use this method asyncContext.signalContextSwitch();

try { Thread.sleep(500); } catch (InterruptedException e) { e.printStackTrace(); } asyncContext.write("Hello " + name + ", response from provider."); // only reset after asyncContext.write() asyncContext.resetContext(); }).start(); return null; } } public class AsyncServiceImpl implements AsyncService { public CompletableFuture sayHello(String name) { CompletableFuture future = new CompletableFuture(); final AsyncContext asyncContext = RpcContext.startAsync(); new Thread(() -> { // the right place to use this method asyncContext.signalContextSwitch(); // some operations... future.complete(); // only reset after future.complete() asyncContext.resetContext(); }).start(); return future; } }

指定者:

resetContext 在接口中 AsyncContext

getInternalFuture

public CompletableFuture<Object> getInternalFuture()
