Interface AsyncRequestHandler

public interface AsyncRequestHandler

Service whose implementations define whether a given request should be handled asynchronously or not and, if yes, which Executor (usually, a thread pool, but not necessarily) should handle it, possibly different HttpServletRequest and HttpServletResponse objects to be used when calling HttpServletRequest#startAsync()} and an optional AsyncListener.

If one AsyncRequestHandler doesn't tells the request should be asynchronous, the next one contributed to AsyncRequestService will be called and so on until one says the request should be asynchronous or all of them were called and the request will be synchronous.
