Class and Description
AsyncContext Class representing the execution context for an asynchronous operation that was initiated on a ServletRequest.
AsyncEvent Event that gets fired when the asynchronous operation initiated on a ServletRequest (via a call to ServletRequest.startAsync() or ServletRequest.startAsync(ServletRequest, ServletResponse)) has completed, timed out, or produced an error.
AsyncListener Listener that will be notified in the event that an asynchronous operation initiated on a ServletRequest to which the listener had been added has completed, timed out, or resulted in an error.
DispatcherType Enumeration of filter dispatcher types.
Filter A filter is an object that performs filtering tasks on either the request to a resource (a servlet or static content), or on the response from a resource, or both.
FilterChain A FilterChain is an object provided by the servlet container to the developer giving a view into the invocation chain of a filtered request for a resource.
FilterConfig A filter configuration object used by a servlet container to pass information to a filter during initialization.
FilterRegistration Interface through which a Filter may be further configured.
