Dynamic Bitset - Upcoming Formal Review
by Mat Marcus 03 Jun '02

03 Jun '02

The formal review of Dynamic Bitset by Chuck Alison and Jeremy Siek will commence on Saturday June 8th and run through Monday, June 17th. The library is currently available at <http://groups.yahoo.com/group/boost/files/dyn_bitset.tar.gz> Below is an excerpt from the library's documentation: The dyn_bitset class represents a set of bits. It provides accesses to the value of individual bits via an operator[] and provides all of the bitwise operators that one can apply to builtin integers, such as operator&& and operator<<. The number of bits in the set is specified at runtime via a parameter to the constructor of the dyn_bitset. Each bit represents either the Boolean value true (set) or false (reset). To toggle a bit is to change the value to true if it is false and to false if it is true. Each bit has a non-negative position pos. The position pos == 0 corresponds to the least significant bit and pos == size() - 1 is the most significant bit. When converting an instance of dyn_bitset to or from an unsigned long, the bit position pos corresponds to the bit value 1 << pos. The dyn_bitset class is nearly identical to the std::bitset class. The difference is that the size of the dyn_bitset (the number of bits) is specified at run-time during the construction of a dyn_bitset object, whereas the size of a std::bitset is specified at compile-time through an integer template parameter. For information about submitting a Formal Review, see http://www.boost.org/more/formal_review_process.htm Please try out the library so that you will be prepared to to say whether or not you think the library should be accepted by Boost during the upcoming review period next week Compiler notes: This library has been tested using the following compiler platforms: Gcc 2.95 and 3.01 Kai C++ Metrowerks Codewarrior 8 (beta, Mac) The library presently requires template friend support and therfore is known not to compile with CodeWarrior 7.2. The library has not been tested with VC++ or Borland. The Formal Review manager will be Mat Marcus.
