I’ve been thinking on and off about the appropriate return signature for a method that returns an immutable list of objects, sparked off by reading Eric Lippert’s article, Arrays considered somewhat harmful, and my belief that the value of functional program and growth of parallelism means that immutability is desirable most of the time.
However, once you decide to return an immutable collection, what type do you return?
It’s a waste of processor cycles and user time to make web service calls to systems that are not currently functioning. I was involved in building a solution that allows code that depends on non-functioning systems to be skipped entirely. Code simply needs to be attributed with the systems it uses. Then a policy injection handler will throw an exception without even calling that code if a system is known to be unavailable.
