Method Detail

singleton

public static Nad2Nad singleton()

This is synchronized because it can get called from the GPS device thread and the GUI thread, and there is a race condition where both threads see that instance is null and initialize it. The double initialization was causing some strange errors. You wanna see the errors? You wanna know what they are? You can't handle them. They are too much. Too, too much.

Returns:
