Class AsyncStateMachine

java.lang.Object
  extended by org.apache.coyote.AsyncStateMachine

public class AsyncStateMachine
extends Object

Manages the state transitions for async requests. TODO: State transition diagram The internal states that are used are: DISPATCHED - Standard request. Not in Async mode. STARTING - ServletRequest.startAsync() has been called but the request in which that call was made has not finished processing. STARTED - ServletRequest.startAsync() has been called and the request in which that call was made has finished processing. MUST_COMPLETE - complete() has been called before the request in which ServletRequest.startAsync() has finished. As soon as that request finishes, the complete() will be processed. COMPLETING - The call to complete() was made once the request was in the STARTED state. May or may not be triggered by a container thread - depends if start(Runnable) was used TIMING_OUT - The async request has timed out and is waiting for a call to complete(). If that isn't made, the error state will entered. MUST_DISPATCH - dispatch() has been called before the request in which ServletRequest.startAsync() has finished. As soon as that request finishes, the dispatch() will be processed. DISPATCHING - The dispatch is being processed. ERROR - Something went wrong.
