This interface is designed to be a callback mechanism from the SelectorManager. Once the manager has determines that something has happened, it informs the appropriate SelectionKeyHandler via this interface. The SelectionKeyHandler which is interested in being notified of events relating to the SelectionKey should attach itself to the SelectionKey via the attach() method. The SelectorManager will then call that SelectionKeyHandler's methods.
