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

       o   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.

       o   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.

	   See "Constructors" in Mail::Field

       Mail::Field::Date->new(TAG [, STRING | OPTIONS])

       $obj->set(OPTIONS)
	    -Option --Default
	     Time     undef
	     TimeStr  undef

	   Time => SECONDS

DIAGNOSTICS

       Error: Undefined subroutine <method> called
	   Mail::Field objects use autoloading to compile new functionality.  Apparently, the method called is not implemented for the specific
	   class of the field object.
