Throwing TXBase Exceptions

After you have created or cloned a TXBase object, you can throw the object in two ways:

• Use the throw keyword followed by the object name, as follows:

  TXBase xobj("Some exception...");
  throw xobj;

• Call the exception object's Throw function, as follows:

  TXBase xobj("Some exception...");
  xobj.Throw();

  This last method provides strict type safety when you throw the exception. It also provides a polymorphic interface when throwing the exception, allowing the function that catches a TXBase-derived exception object to treat the object as a TXBase object, regardless of what it actually is.
