If you want to create an ExplicitBitVect from a bit string, the appropriate invocation is; ExplicitBitVect *res=new ExplicitBitVect(bits.length()); FromBitString(*res,bits); Note that if you are just interested in storing the bit vectors on disk in an efficient way and are ok if that's not human readable, then it would be better to either: - write the pickled form into your output files using BitVectToBinaryText() and then using ExplicitBitVect(text) when you read them in or - write the FPS form using BitVectToFPSText() and then create new bit vects like this when you read those in: ExplicitBitVect *res=new ExplicitBitVect(fps.length()*4); UpdateBitVectFromFPSText(*res,fps); Both the binary format and the FPS format are smaller on disk. -greg ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
