The Exceptions Mechanism
Exceptions provide a mechanism for dealing with
unusual circumstances in programs. The exception classes have the
following characteristics:
- A stack of exception message text strings.
These strings allow you to describe the exception in
detail.
- An error ID that lets you uniquely
identify what error caused the exception.
- A severity code that lets you determine
whether the exception can be recovered from or not.
- Information about where the exception was
thrown.
The exception classes' member functions allow
you to:
- Add information about where the exception
was thrown.
- Add text to the description of the
exception.
- Get the error ID of the exception.
- Determine if the exception is recoverable.
- Log the exception data.
- Set the error ID of the exception.
- Set the severity of the exception.
- Set a trace function.
