hi,
i've got an interface to load an arbitrary number of files, where each
load operation may fail independently, but any failure should not abort
the whole operation. so i'd like to throw some kind of compound
exception at the end if at least 1 error occurred.
That seems backwards.
If a single failure means that the entire operation is considered
failed, you should abort with that single exception as soon as the error
occurs. If possible roll back the things you already did first.
If failure of a suboperation is NOT a failure of the entire operation,
then this should be treated as a qualified success. That means it
shouldn't throw, but return, possibly passing out a tally of what worked
and failed. So returning a collection of objects that describes the
status of each suboperation (possibly including the exception object you
caught) would seem to be the more appropriate solution.
