| Summary : Inheritable, overridable class data
|
Description :
Class::Data::Inheritable is for creating accessor/mutators to class data.
That is, if you want to store something about your class as a whole
(instead of about a single object). This data is then inherited by your
subclasses and can be overridden.
For example:
Pere::Ubu->mk_classdata(\'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;
The interesting part happens when a class inherits from Pere::Ubu:
package Raygun;
use base qw(Pere::Ubu);
$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:
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->Suitcase(\'Orange\');
Now that Raygun has overridden Pere::Ubu further changes by Pere::Ubu no
longer effect Raygun.
Pere::Ubu->Suitcase(\'Samsonite\');
