Do you have a test case that you can share?
This isn't a classic endian issue. I just needed to know in what order the bits were arranged within each block. This didn't match the bit ordering from the source I had.
For masking out the ith bit in a block, it uses 1 shifted left by i. As a result, the bits are not consecutive.
What do you mean by "consecutive"? Why do you think this matters?
If one has a need to use the raw memory managed by the bitset for some purpose one needs to know the ordering. Also, if one needed to change the block_type for that chunk of raw memory it would matter.
(I have just had a quick look at the code, and I've not seen anything like casts or unions that could cause endianness issues.)
You are right
Regards, Phil.
Thanks Phil. I do think the ordering should be documented for the constructor that takes start and end block iterators. Joel
