> SequenceFile.rawValue() provides the only interface to navigate the underlying bytes.
And with some little work on implementing a customized ValueBytes can avoid reading all bytes
into memory. Unfortunately, the current nextRawValue will cast the passing ValueBytes to either
private class CompressedBytes or private class UnCompressedBytes, this will disallow user
further extension.
> I can not see any reason that CompressedBytes and UnCompressedBytes should be set to
private. And since the ValueBytes is public and nextValue() casts it to either CompressedBytes
or UnCompressedBytes, i think it would be better if they are public.
> I am stuck now by this issue, really appracited if this got resolved as soon as possible.
