- =head1 NAME
- Class::Accessor::Fast - Faster, but less expandable, accessors
- =head1 SYNOPSIS
- package Foo;
- use base qw(Class::Accessor::Fast);
- # The rest is the same as Class::Accessor but without set() and get().
- =head1 DESCRIPTION
- This is a faster but less expandable version of Class::Accessor.
- Class::Accessor's generated accessors require two method calls to accompish
- their task (one for the accessor, another for get() or set()).
- Class::Accessor::Fast eliminates calling set()/get() and does the access itself,
- resulting in a somewhat faster accessor.
- The downside is that you can't easily alter the behavior of your
- accessors, nor can your subclasses. Of course, should you need this
- later, you can always swap out Class::Accessor::Fast for
- Class::Accessor.
- Read the documentation for Class::Accessor for more info.
