public class NativeBytes<U>
extends VanillaBytes<U>

NativeBytes is a subclass of VanillaBytes which can wrap either a ByteBuffer or malloc'ed memory. It provides flexibility in handling byte arrays which can be of arbitrary sizes and can grow dynamically. The class is called NativeBytes because it deals with 'native' ByteBuffers or memory directly allocated from the operating system which is on heap. It is also capable of handling memory allocation, resizing, and checking boundaries to prevent overflows.

The class can be parameterized with a type which represents the underlying type that the byte buffers are intended to represent. This provides a way to use NativeBytes for any type that can be represented as bytes.
