> org.apache.derby.impl.drda.DDMWriter uses a byte array as a buffer. Wrapping
> the array in a java.nio.ByteBuffer has some advantages, for instance:
> - utility methods for encoding primitive types into the byte array could be
> used instead of manually encoding the values
> - it allows us to encode strings directly into the buffer (using a
> CharsetEncoder) without doing an expensive String.getBytes(String encoding)
> in an intermediate step
> By using a utility class, the code becomes easier to maintain. Also,
> ByteBuffer allows us to access the backing byte array without going through
> the ByteBuffer interface, so we still have the possibility to modify the byte
> array directly in cases where that's more convenient.
