Class Description
WOAdaptor is an abstract class that represents objects that can receive events from a WebObjects adaptor. A WebObjects adaptor is a process that handles communication between the server and a WebObjects application. The WebObjects application (a WOApplication instance) communicates with the adaptor using messages defined in the WOAdaptor class.
The purpose of the WOAdaptor class is to perform these tasks:
Returns whether repeatedly invoking runOnce would result in busy waiting.
dispatchesRequestsConcurrently
- (BOOL)dispatchesRequestsConcurrently
Returns YES if the adaptor is multi-threaded, NO otherwise. If the adaptor is multi-threaded, the adaptor may dispatch requests to the application concurrently in separate threads.

initWithName:arguments:
- (id)initWithName:
(NSString *)aName arguments:
(NSDictionary *)someArguments
Initializes a WOAdaptor with the name aName and arguments someArguments. aName is the name of the WOAdaptor subclass. someArguments are the default options specified for this adaptor (such as port number and listen queue depth).
The WOApplication method adaptorWithName:arguments: invokes this message when it encounters an WOAdaptor option on the command line. The WOApplication retains each of its WOAdaptors.

registerForEvents
- (void)registerForEvents
Performs any actions necessary to have the WOAdaptor start receiving events.
See also: - runLoop in WOApplication
runOnce
- (void)runOnce
Invoked by the application's main loop

unregisterForEvents
- (void)unregisterForEvents
Undoes the actions performed in registerForEvents so that the WOAdaptor stops receiving events.
