throw vs the result

[xbury.cs at clearstream.com]

Interesting coincidence...

This came into my mailbox today...

although it's for C++, it's quite to the point...

quote:
Report an error (e.g., write throw ) wherever a function detects an error that it cannot resolve itself and 
that makes it impossible for the function to continue execution. (See Item 
70)
Handle an error (e.g., write a catch that doesn't rethrow the same or another exception or emit another kind of 
error code) in the places that have sufficient knowledge to handle the 
error, including to enforce boundaries defined in the error policy (e.g., 
on main and thread mainlines; see Item 62) and to absorb errors in the bodies of 
destructors and deallocation operations.
end quote
