[FTR, I've noticed the same thing when I started to use the Java bindings. Back then, this made me wonder whether the bindings are actually used by someone, because the constants are rather useless without being public and nobody objected...] At Fri, 21 Mar 2014 14:05:26 -0600, Yoshikazu Nojima wrote: NACK as I'm planning on fixing this in a different way. With the current approach, there are a few reasons why I'm wishing to avoid this change: 1. the names are too long [we don't have to use a prefix for variable names, since there are other means of scoping in Java (namely namespaces and classes/interfaces)] 2. using int as a flags argument is not type safe and it entices the use of magic numbers in the code So, the plan is to use enums and variable arguments for the API and deprecate the use of the constructors and methods with an integer flag argument; similar to the patch I've posted here[1]. If you want to help push the Java bindings into this direction, you're more than welcome. At first, thanks for your contribution! There's just one minor thing, we prefer to receive patches as single messages, not as attachments. Best way is to use "git send-email", see http://libvirt.org/hacking.html#patches. And it would be nice if you could indicate the project/binding you're working on in the subject using the phrase "[java]" which you can achieve using "git config format.subjectprefix 'java] [PATCH'" when using "git send-email".
