Rob Bagby continued his outstanding presentations with not just an overview of the Exception Handling Block, but a full-blown strategy for handling exceptions. Rob had 5 goals for the session which I have paraphrased below:

1. Understand when and why to catch an exception

   To Recover from the error (or attempt to)

   To Add Context

   To Clean up (close connections, etc)

   To Log or Notify

   To hide the details of an exception

2. Understand the categories of exceptions

   Business

   Technical

   Security

3. Understand what is truly an exception

   Don't use exceptions for flow-control

4. Understand Exception Propogation Options

   Automatic Propogation (bubbling)

   Catch & Rethrow

   Clean

   Resolve

   Log

   Catch, Wrap & Throw Wrapped

5. Understand Custom Exceptions and When to Use Them

when an appropriate exception doesn't already exist

To add discreet handling

To add a specific behavior or information

Rob went into quite a few specifics on exactly how this information could be utilized which is in the slide decks that I will link to asap.

This session got my vote as the most useful session of the day. Thanks Rob!
