public abstract class UserQuestionException
extends java.io.IOException

Exception that is thrown when the process is about to perform some action that requires user confirmation. It can be useful when there is a call to a method which cannot open a dialog, but still would like to ask the user a question. It can raise this exception and higher level parts of the system can/should catch it and present a dialog to the user and if the user agrees reinvoke the action again.

The getLocalizedMessage method should return the user question, which will be shown to the user in a dialog with OK, Cancel options and if the user chooses OK, method ex.confirmed () will be called.
