Java Buffers

IntBuffer buff = BufferUtils.createIntBuffer(8);

// First I want it to contain [1, 1, 1, 1]
buff.put(new int[]{1, 1, 1, 1});

// Now I have to read this data, so I flip it
buff.flip();

// Now I want the buffer to contain [1, 1, 1, 1, 2, 2]
//how? the limit is now 4, so I cannot write more than 4 elements...
