Classes
interface	OnKeyEventHandledCallback

Public Member Functions
void	handleEvent ( @NonNull KeyEvent keyEvent, @NonNull OnKeyEventHandledCallback onKeyEventHandledCallback)

Detailed Description

The interface for responding to a KeyEvent asynchronously.

Implementers of this interface should be owned by a KeyboardManager, in order to receive key events.

After receiving a KeyEvent, the Responder must call the supplied OnKeyEventHandledCallback exactly once, to inform the KeyboardManager whether it wishes to handle the KeyEvent. The KeyEvent will not be propagated to the TextInputPlugin or be redispatched to the view hierachy if any key responders answered yes.

If a Responder fails to call the OnKeyEventHandledCallback callback, the KeyEvent will never be sent to the TextInputPlugin, and the KeyboardManager class can't detect such errors as there is no timeout.
