public ByteBufferOutputStream(ByteBuffer bb)
bb - ByteBuffer to use. If too small, will be discarded and a new one allocated in its
place; i.e. the passed in BB may NOT BE RETURNED!! Minimally it will be altered. SIDE EFFECT!!
If you want to get the newly allocated ByteBuffer, you'll need to pick it up when
done with this instance by calling getByteBuffer(). All this encapsulation violation
is so we can recycle buffers rather than allocate each time; it can get expensive especially
if the buffers are big doing allocations each time or having them undergo resizing because
initial allocation was small.getByteBuffer()public int size()
