38. Trace - Simple or Robust
• Numbers only
OR
• Dynamic State
• Static State
• Engine State
• Behavior Name
• Etc.

39. Trace Can be Inherited
• True Trace Definition • False Trace Definition
– Subordinate Call to True – Subordinate Call to False
Trace Trace
• Subordinate Call to True • Subordinate Call to False
Trace Trace
– Subordinate Call to True – Subordinate Call to False
Trace Trace

40. Trace Can Be:
• Enabled • Disabled
– Dynamic bind = – Dynamic bind =
call to Trace call to ignore

44. Was improving the quality of your software products a company goal?
Are you using an object-oriented design methodology because it promotes code
reuse and reduces code maintenance and complexity?
Are you happy with the results? Or did you end up with spaghetti objects?
My new book provides a clear step-by-step of how to achieve the promise that
object technology alone can t deliver.
can’t deliver
But it requires change.
