The following module was proposed for inclusion in the Module List: modid: Data::BitMask DSLIP: RdpOa description: Bitmask manipulation userid: TEVERETT (Toby Ovod-Everett) chapterid: 6 (Data_Type_Utilities) communities:
similar: rationale: Namespace choice was recommended by Tim Bunce (http://www.xray.mpe.mpg.de/mailing-lists/modules/2003-08/msg00342.html). Using C-style constants (i.e. global or semi-global values or subroutines) is a bad approach to supporting bitmasks in modules for a number of reasons. First, it allows for inaccurate specification of bitmasks (i.e. allowing the use of constants authorized for a given situation in other situations where the constant does not accurately describe the bitmask in question), causing potential problems in code maintenance. Second, it provides no easy way to break a bitmask back into its constituent constants. Third, it relies upon the user to do all of the bitmask manipulation. Many module users do not have a solid understanding of the bitwise operations necessary to do the manipulation properly, which can lead to bugs in code. This module attempts to address all of those concerns. enteredby: TEVERETT (Toby Ovod-Everett) enteredon: Sun Sep 7 16:55:06 2003 GMT The resulting entry would be: Data:: ::BitMask RdpOa Bitmask manipulation TEVERETT Thanks for registering, -- The PAUSE PS: The following links are only valid for module list maintainers: Registration form with editing capabilities: https://pause.perl.org/pause/authenquery?ACTION=add_mod&USERID=08400000_522003f3d3adbab8&SUBMIT_pause99_add_mod_preview=1 Immediate (one click) registration: https://pause.perl.org/pause/authenquery?ACTION=add_mod&USERID=08400000_522003f3d3adbab8&SUBMIT_pause99_add_mod_insertit=1
