Method Summary

Modifier and TypeMethod and Description
public void
complete()

Implements org.springframework.http.server.ServerHttpAsyncRequestControl.complete.

Mark asynchronous request processing as completed.
public boolean
isCompleted()

Implements org.springframework.http.server.ServerHttpAsyncRequestControl.isCompleted.

Return whether asynchronous request processing has been completed.
public boolean
isStarted()

Implements org.springframework.http.server.ServerHttpAsyncRequestControl.isStarted.

Return whether asynchronous request processing has been started.
public void
onComplete(AsyncEvent
Provides access to the objects associated with the event
event)

Implements jakarta.servlet.AsyncListener.onComplete.

This event is fired after the call to AsyncContext#complete() has been processed by the container.
public void
onError(AsyncEvent
Provides access to the objects associated with the event
event)

Implements jakarta.servlet.AsyncListener.onError.

This event is fired if an error occurs during an asynchronous operation but before the container takes any action as a result of the error.
public void
onStartAsync(AsyncEvent
Provides access to the objects associated with the event
event)

Implements jakarta.servlet.AsyncListener.onStartAsync.

This event is fired if new call is made to ServletRequest#startAsync() after the completion of the AsyncContext to which this listener was added.
public void
onTimeout(AsyncEvent
Provides access to the objects associated with the event
event)

Implements jakarta.servlet.AsyncListener.onTimeout.

This event is fired if an asynchronous operation times out but before the container takes any action as a result of the timeout.
public void
start()

Implements org.springframework.http.server.ServerHttpAsyncRequestControl.start.

Enable asynchronous processing after which the response remains open until a call to complete() is made or the server times out the request.
public void
start(long timeout)

Implements org.springframework.http.server.ServerHttpAsyncRequestControl.start.

A variation on start() that allows specifying a timeout value to use for asynchronous processing.
