NAME

Class::MakeMethods::Template::ClassInherit - Overridable class data

SYNOPSIS

  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();    # Intially same as superclass,
  MySubClass->foo('Foobar');  # but overridable per subclass/

DESCRIPTION

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.

Standard Methods

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 ALSO

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.
