Oct 11, 2022 at 0:15	comment	added	Ed Swangren		@pqnet: if init() fails, what then? Throw an exception? What's the advantage exactly? You just lost the stack trace along with everything else, and why couldn't that have been handled just as well in the constructor to begin with? Useless wrapper methods are a pain
Jan 28, 2020 at 15:28	comment	added	CharonX		@pqnet With `init()` methods I see the issue that you end up with temporal coupling. You can do `X` with this class, but you have to `init()` it first. So now you need to add checks to every function call if the class is really initialized and handle the possible failure events...
Mar 12, 2018 at 11:27	comment	added	pqnet		the advantage, in my opinion, of the `init` method is that handling failure is a lot easier. In particular, the return value of the `init` method can indicate whether initialization is successful, and the method can ensure the object is always in a good state.
