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:

WOAdaptor

public WOAdaptor(java.lang.String aName, 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.

Instance Methods


doesBusyRunOnce

public boolean doesBusyRunOnce()

Returns whether repeatedly invoking runOnce would result in busy waiting.


dispatchesRequestsConcurrently

public boolean dispatchesRequestsConcurrently()

Returns true if the adaptor is multi-threaded, false otherwise. If the adaptor is multi-threaded, the adaptor may dispatch requests to the application concurrently in separate threads.

See also: adaptorsDispatchRequestsConcurrently (WOApplication)


registerForEvents

public void registerForEvents()

Performs any actions necessary to have the WOAdaptor start receiving events.

See also: runLoop in WOApplication


runOnce

public void runOnce()

Invoked by the application's main loop

See also: doesBusyRunOnce


unregisterForEvents

public void unregisterForEvents()

Undoes the actions performed in registerForEvents so that the WOAdaptor stops receiving events.
