The Params::Validate module provides a flexible system for validation method/function call parameters. The validation can be as simple as checking for the presence of required parameters or as complex as validating object classes (via isa) or capabilities (via can), checking parameter types, and using customized callbacks to ensure data integrity. The module has been designed to work equally well with positional or named parameters (as a hash or hash reference). It includes both a fast XS implementation, and a slower pure Perl implementation that it can fall back on. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install If you do not have a C compiler on your machine, then the pure Perl implementation will be installed. If you have problems compiling the C version, then run "perl Makefile.PL --pm" to specify that only the pure Perl version should be tested and installed. BUGS/PROBLEMS The XS version may segfault with Perl 5.6.0 under certain conditions. When using the pure Perl version, trying to run the test suite with Perl 5.6.0 on my machine caused repeated core dumps, though 5.00503 is fine. Perl 5.6.0 is known to be buggy, and upgrading to 5.6.1 is strongly recommended. COPYRIGHT AND LICENSE Copyright (c) 2000-2003 Dave Rolsky All rights reserved.
