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
  6. 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!
