public static interface IExceptionHandler2

Classes implementing this interface know how to handle ParameterExceptions (usually from invalid user input) and ExecutionExceptions that occurred while executing the Runnable or Callable command.

Implementations of this interface can be passed to the

parseWithHandlers(IParseResultHandler2, IExceptionHandler2, String...) method.

This interface replaces the IParseResultHandler interface.
