> If MemoryManager implemented something like a ByteBuffer allocate(int size) then I could
be used to directly transfer data to/from Files and Sockets without having to first copy them
to a byte[].
> I'm not talking about using the ByteBuffer.allocate call. I'm talking about adding a
method to MemoryManager:
> ByteBuffer bb = MemoryManager.allocate(1024*1024);
> So that I can directly modify the ByteBuffer using Channels to avoid a memory copy..
Compare this to using the MemoryManager store, update, and retrieve calls. They all force
you to work with byte[]s so you end up doing a memory copies into and out of direct memory.
