so, you want to have access to (line 52)
/**
* Points always to the first element of the id buffer.
*/
final NativeSizeBuffer IDsView;
problem is that if i would expose it and anyone would change the buffer
position (e.g unintentionally by iterating through it) the list would be
broken.
The variable is package private. Would it be OK for you to write a
utility and place it in com.jogamp.opencl to access the buffer?
buffer = Hack.get(events);
Or maybe you have a better idea how to solve that..

I am using NativeSizeBuffer* in my repository for size_t to separate
both types (and other reasons). However if you want to stay compatible
with jogamp you probably better stick with PB.

thanks. It should make a few scenarios less verbose (and therefore
easier to read which is often my goal).
The next blog entry will focus on actual features (concurrent package).
