I meant if you're trying to *implement* serialisation. The Bits
class allows you to access bits one by one, but surely you'd want some way to know how many bits you need to keep?
I think that falls into the realm of protocol design; if you're doing it in your program at runtime, you're probably doing it wrong. (The fixed size version makes sense for marshaling; it's *dynamic* sizes that need to be thought out beforehand.)
If you're doing, say, cryptography, then thousand-bit random integers that need to be serialised are fairly common...
Sure, and there are encodings that let you do this without needing bitSize (BER). You need a word count, but that's usually part of the structure holding the integer. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
