Throw Exceptions from setters: second opinion
Hi all,
Recently somebody on a forum told me, and nearly convinced me, that
throwing Exceptions from setters is bad practice. He stated that setters
should only return boolean false if the provided input is not valid, since
that is what they are expected to do: validate input and simply tell
wheter it's valid or not. Furthermore he stated that throwing Exceptions
is only meaningful when an internal routine of the class encounters
invalid data. Does this sound reasonable to you? I'm not sure yet myself.
Love to hear your opinions on the matter.
Thanks in advace.
