It would have been useful to get agreement on the concept and the naming before committing to the implementation. The BE/BO/LE are noise in the API. The little endian cases are a minority and should attract more attention in the API. The network byte-order/big-endian cases should keep the simple names. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23478#issuecomment-2640004192
