%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);
|
|
|
|
# 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');
