DESCRIPTION

This is the Catalyst Model Class called Catalyst::Model::Proxy that implements Proxy Design Pattern. It enables you to make calls to target classes/subroutines via proxy mechanism. This means reduced memory footprint because any operations performed on the proxies are forwarded to the original complex ( target_class ) object. The target class model is also cached for increased performance. For more information on the proxy design pattern please refer yourself to: http://en.wikipedia.org/wiki/Proxy_design_pattern
