# NAME Class::Data::Lazy - Create class data with laziness. # SYNOPSIS use Class::Data::Lazy qw( foo ); Is equivalent to: sub foo { my $class = shift; my $value = $class->_build_foo; *{"${class}::foo"} = sub { $value }; return $value; } # DESCRIPTION Class::Data::Lazy is lazy class data maker. I want to write lazy class accessor. # MOTIVATION When I'm writing a context class for web application, some thing need lazy building. For example: package MyApp; use Class::Data::Lazy qw( memcached ); sub _build_memcached { my $class = shift; my $conf = $class->config->{'Cache::Memcached::Fast'} or die "Missing configuration for Cache::Memcached::Fast"; Cache::Memcached::Fast->new($conf); } Q. Why should it be lazy class method? A. Because `$class->config` is not available when the class is loading. # LICENSE Copyright (C) tokuhirom.
