%description
*This module is now deprecated!*

Please consider using the Class::Accessor::Grouped manpage or the Moose
manpage

Class::Data::Accessor is the marriage of the Class::Accessor manpage and
the Class::Data::Inheritable manpage into a single module. It is used for
creating accessors to class data that overridable in subclasses as well as
in class instances.

For example:

Pere::Ubu->mk_classaccessor('Suitcase');

will generate the method Suitcase() in the class Pere::Ubu.

This new method can be used to get and set a piece of class data.

Pere::Ubu->Suitcase('Red');
  $suitcase = Pere::Ubu->Suitcase;

Taking this one step further, you can make a subclass that inherits from
Pere::Ubu:

package Raygun;
  use base qw(Pere::Ubu);

# Raygun's suitcase is Red.
  $suitcase = Raygun->Suitcase;

Raygun inherits its Suitcase class data from Pere::Ubu.

Inheritance of class data works analogous to method inheritance. As long as
Raygun does not "override" its inherited class data (by using Suitcase() to
set a new value) it will continue to use whatever is set in Pere::Ubu and
inherit further changes:

# Both Raygun's and Pere::Ubu's suitcases are now Blue
  Pere::Ubu->Suitcase('Blue');

However, should Raygun decide to set its own Suitcase() it has now
"overridden" Pere::Ubu and is on its own, just like if it had overridden a
method:

# Raygun has an orange suitcase, Pere::Ubu's is still Blue.
  Raygun->Suitcase('Orange');

Now that Raygun has overridden Pere::Ubu, further changes by Pere::Ubu no
longer effect Raygun.

# Raygun still has an orange suitcase, but Pere::Ubu is using Samsonite.
  Pere::Ubu->Suitcase('Samsonite');

You can also override this class data on a per-object basis. If $obj isa
Pere::Ubu then

$obj->Suitcase; # will return Samsonite

$obj->Suitcase('Purple'); # will set Suitcase *for this object only*

And after you've done that,

$obj->Suitcase; # will return Purple

but

Pere::Ubu->Suitcase; # will still return Samsonite

If you don't want this behaviour use the Class::Data::Inheritable manpage
instead.

'mk_classaccessor' will die if used as an object method instead of as a
class method.
