Static to the top as well here please.

[René Jeschke, 2014/03/31 09:10:38]

Hm, those static methods are exported through JNI and don't seem to fit the
'normal' static case, so are you sure I should put those on the top?

[Felix Dahlke, 2014/03/31 10:43:23]

IMO yes, unnamed namespace should work all the same after all.

[René Jeschke, 2014/04/11 12:25:53]

Done.
