[mkgmap-dev] Merge from the multipolygon branch.From Chris Miller chris.miller at kbcfp.com on Tue Sep 15 00:17:22 BST 2009
As far as I'm aware, declaring a method final doesn't make a whole lot of difference to hotspot these days. Hotspot can still inline a method if it's not declared final but determines at runtime it's not overriden elsewhere. If some new code eventually turns up that does override the method, hotspot will 'uninline' the method dynamically. http://www.java2s.com/Article/Java/JVM/The_Java_HotSpot_Performance_Engine_Method_Inlining_Example.htm The only real reason that I'm aware of for declaring a method final is to deliberately prevent it from being overridden as a design decision.
