You can create your very own implementation of Bytes by extending the AbstractBytes class.

You will need to implement the following functions:

• get(i)
• size()
• slice(offset, size)
• copy(offset, size)
• mutableCopy(offset, size)

You can choose to simplify greatly by extending the DelegatingBytes class instead.
