FreezeThaw is a Perl module for converting Perl structures to strings and back. SYNOPSIS use FreezeThaw qw(freeze thaw cmpStr safeFreeze cmpStrHard); $string = freeze $data1, $data2, $data3; ... ($olddata1, $olddata2, $olddata3) = thaw $string; if (cmpStr($olddata2,$data2) == 0) {print "OK!"} Converts data to/from stringified form, appropriate for saving-to/reading-from permanent storage. Deals with objects, circular lists, repeated appearence of the same refence. Does not deal with overloaded stringify operator yet. EXPORT Exportable freeze thaw cmpStr cmpStrHard safeFreeze. User API cmpStr analogue of cmp for data. Takes two arguments and compares them as separate entities. cmpStrHard analogue of cmp for data. Takes two arguments and compares them considered as a group. freeze returns a string that encupsulates its arguments (considered as a group). thawing this string leads to a fatal error if arguments to freeze contained references to GLOBs and CODEs. safeFreeze returns a string that encupsulates its arguments (considered as a group). The result is thawable in the same process. thawing the result in a different process should result in a fatal error if arguments to safeFreeze contained references to GLOBs and CODEs. thaw takes one string argument and returns an array. The elements of the array are "equivalent" to arguments of the freeze command that created the string. Can result in a fatal error (see above). Limitations:.
