Constructor	Description
`ServletServerHttpAsyncRequestControl(ServletServerHttpRequest request, ServletServerHttpResponse response)`	Constructor accepting a request and response pair that are expected to be of type `ServletServerHttpRequest` and `ServletServerHttpResponse` respectively.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`complete()`	Mark asynchronous request processing as completed.
`boolean`	`isCompleted()`	Return whether asynchronous request processing has been completed.
`boolean`	`isStarted()`	Return whether asynchronous request processing has been started.
`void`	`onComplete(AsyncEvent event)`
`void`	`onError(AsyncEvent event)`
`void`	`onStartAsync(AsyncEvent event)`
`void`	`onTimeout(AsyncEvent event)`
`void`	`start()`	Enable asynchronous processing after which the response remains open until a call to `ServerHttpAsyncRequestControl.complete()` is made or the server times out the request.
`void`	`start(long timeout)`	A variation on `ServerHttpAsyncRequestControl.start()` that allows specifying a timeout value to use to use for asynchronous processing.

```
public boolean isStarted()
```
    Description copied from interface: ServerHttpAsyncRequestControl
    Return whether asynchronous request processing has been started.
    Specified by:
    isStarted in interface ServerHttpAsyncRequestControl
  - isCompleted
```
public boolean isCompleted()
```
    Description copied from interface: ServerHttpAsyncRequestControl
    Return whether asynchronous request processing has been completed.
    Specified by:

  - start
```
public void start()
```
    Description copied from interface: ServerHttpAsyncRequestControl
    Enable asynchronous processing after which the response remains open until a call to ServerHttpAsyncRequestControl.complete() is made or the server times out the request. Once enabled, additional calls to this method are ignored.
    Specified by:
    start in interface ServerHttpAsyncRequestControl

```
public void start(long timeout)
```
    Description copied from interface: ServerHttpAsyncRequestControl
    A variation on ServerHttpAsyncRequestControl.start() that allows specifying a timeout value to use to use for asynchronous processing. If ServerHttpAsyncRequestControl.complete() is not called within the specified value, the request times out.
    Specified by:
    start in interface ServerHttpAsyncRequestControl
  - complete
```
public void complete()
```
    Description copied from interface: ServerHttpAsyncRequestControl
    Mark asynchronous request processing as completed.
