Data::Predicate This is a library inspired by Apache Commons Collection Predicate library and google-collections Predicate library (both Java libraries). Predicates are transportable logic objects which boil down to a true/false response. A number of predicates have already been built allowing for the combination of multiple predicates (and), partial matching (or) or reverse logic (not). These mixed in with more complex & Perl centric ideas (defined, number isa) allows us to build very complex logic in portions and then build a final logic Object to represent the boolean concept. Predicates are not meant to replace normal if statement logic; more to supplement it. Data::Predicate is the core class & default implementations are available from Data::Predicate::Predicates. In time this module may develop an XS library but for the moment it is written in PurePerl (for better or worse). INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Data::Predicate You can also look for information at: RT, CPAN's request tracker http://rt.cpan.org/NoAuth/Bugs.html?Dist=Data-Predicate AnnoCPAN, Annotated CPAN documentation http://annocpan.org/dist/Data-Predicate CPAN Ratings http://cpanratings.perl.org/d/Data-Predicate Search CPAN http://search.cpan.org/dist/Data-Predicate/ COPYRIGHT AND LICENCE Copyright (c) 2010 - 2010 European Molecular Biology Laboratory.
