TObject |
Exception is the base class for all exception handling routines in the RTL and FCL. While it is possible to raise an exception with any class descending from TObject, it is recommended to use Exception as the basis of exception class objects: the Exception class introduces properties to associate a message and a help context with the exception being raised. What is more, the SysUtils unit sets the necessary hooks to catch and display unhandled exceptions: in such cases, the message displayed to the end user, will be the message stored in the exception class.
