From 710d86d31cd278583ee3d74b36595f4148a72133 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sat, 5 Jun 2010 00:03:49 +0200 Subject: Minor additions to nio/Buffers, util/IntIntHashMap and os/NativeLibrary Buffers add 'float[] getFloatArray(double[])' conversion, ready to replace all JOGL InternalBufferUtil's. NativeLibrary/DynamicLinker add global lookup method allowing Unices and OSX to lookup a symbol globally. However, this is not recommended, due to the lookup costs. Windows is not supported here.
