Tie::Watch An object oriented interface to the Perl builtin tie(), that allows a watchpoint to be placed on any Perl variable. A watchpoint is simply a callback (subroutine) that is invoked when a variable is accessed. The callback can do various things: . alter a variable's value . prevent a variable's value from being changed . invoke a Perl/Tk callback when a variable changes . trace references to a variable Do: perl Makefile.PL make test make install You may find the programs in the .../examples directory interesting. This version supports tied arrays and REQUIRES Perl 5.004_57 or higher. Also, the old Delete() method has been renamed Unwatch() since it conflicted with the builtin delete() function. BUGS: not aware of any. Steve Lidie sol0@Lehigh.EDU 1999/04/04 2005/05/16
