NAME

       Class::Field - Class Field Accessor Generator

SYNOPSIS

           package Thing;
           use Class::Field qw'field const';

           field 'this';
           field 'list' => [];
           field 'map' => {};
           field 'that', -init => '$self->setup_that';
           field 'circular_ref' => -weaken;
           const 'answer' => 42;

DESCRIPTION

       Class::Field exports two subroutines, "field" and "const". These functions are used to
       declare fields and constants in your class.

       Class::Field generates custom code for each accessor that is optimized for speed.

FUNCTIONS

       "field"
           Defines accessor methods for a field of your class:

               package Example;
               use base 'Parent';
               use Class::Field qw'field const';

               field 'foo';
               field bar => [];

               sub lalala {
                   my $self = shift;
                   $self->foo(42);
                   push @{$self->{bar}}, $self->foo;
               }

           The first parameter passed to "field" is the name of the attribute being defined.
           Accessors can be given an optional default value. This value will be returned if no
           value for the field has been set in the object.

       "const"
               const bar => 42;

           The "const" function is similar to <field> except that it is immutable.  It also does
           not store data in the object. You probably always want to give a "const" a default
           value, otherwise the generated method will be somewhat useless.

NOTE

       this code was taken directly out the Spiffy module for those people who just want this
       functionality without using the rest of Spiffy.
