Class::MakeMethods::Template::ClassInherit - Overridable class data
package MyClass;
use Class::MakeMethods( 'Template::ClassInherit:scalar' => 'foo' );
# We now have an accessor method for an "inheritable" scalar value
package main;
MyClass->foo( 'Foozle' ); # Set a class-wide value
print MyClass->foo(); # Retrieve class-wide value
...
package MySubClass;
@ISA = 'MyClass';
print MySubClass->foo(); # Initially same as superclass,
MySubClass->foo('Foobar'); # but overridable per subclass/
The MakeMethods subclass provides accessor methods that search an inheritance
tree to find a value. This allows you to set a shared or default value for a
given class, and optionally override it in a subclass.
The following methods from Generic should all be supported:
scalar
string
string_index (?)
number
boolean
bits (?)
array (*)
hash (*)
tiedhash (?)
hash_of_arrays (?)
object (?)
instance (?)
array_of_objects (?)
code (?)
code_or_scalar (?)
See Class::MakeMethods::Template::Generic for the interfaces and behaviors of
these method types.
The items marked with a * above are specifically defined in this package,
whereas the others are formed automatically by the interaction of this
package's generic settings with the code templates provided by the Generic
superclass.
The items marked with a ? above have not been tested sufficiently; please inform
the author if they do not function as you would expect.
See Class::MakeMethods for general information about this distribution.
See Class::MakeMethods::Template for more about this family of subclasses.
See Class::MakeMethods::Template::Generic for information about the various
accessor interfaces subclassed herein.
If you just need scalar accessors, see Class::Data::Inheritable for a very
elegant and efficient implementation.
