Examples of ch.agent.t2.T2Exception

ch.agent.t2.time.Range
T2Exception is thrown by methods of the Time2 library when they need to throw a checked exception. Such exceptions are so-called "business exceptions" corresponding to logical problems occurring during normal usage of an application. As an example, attempting to force a Sunday date on a time domain where only working days are defined will result in a T2Exception being thrown. The application is supposed to catch the exception and present the accompanying message to the user. @author Jean-Paul Vetterli
