NAME

       Class::MakeMethods::Template::Scalar - Methods for blessed scalars

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Template::ExternalData (
	   new		   => 'new',
	   scalar	   => 'foo',
	 );

	 package main;

	 my $obj = MyObject->new( foo => "Foozle" );
	 print $obj->foo();	       # Prints Foozle
	 $obj->foo("Bamboozle");       # Sets $$obj
	 print $obj->foo();	       # Prints Bamboozle

DESCRIPTION

       Supports the Generic object constructor and accessors meta-method types, but uses scalar refs as the underlying implementation type, so
       only one accessor method can be used effectively.

   Standard Methods
       The following methods from Generic are all supported:

	 new
	 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.

       However, note that due to special nature of this package, all accessor methods reference the same scalar value, so setting a value with one
       method will overwrite the value retrieved by another.

NAME

       Class::MakeMethods::Template::Inheritable - Overridable data

SYNOPSIS

	 package MyClass;

	 use Class::MakeMethods( 'Template::Inheritable:scalar' => 'foo' );
	 # We now have an accessor method for an "inheritable" scalar value

	 MyClass->foo( 'Foozle' );   # Set a class-wide value
	 print MyClass->foo();	     # Retrieve class-wide value

	 my $obj = MyClass->new(...);
	 print $obj->foo();	     # All instances "inherit" that value...

	 $obj->foo( 'Foible' );      # until you set a value for an instance.
	 print $obj->foo();	     # This now finds object-specific value.
	 ...

	 package MySubClass;
	 @ISA = 'MyClass';

	 print MySubClass->foo();    # Intially same as superclass,
	 MySubClass->foo('Foobar');  # but overridable per subclass,
	 print $subclass_obj->foo(); # and shared by its instances
	 $subclass_obj->foo('Fosil');# until you override them...
	 ...

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 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::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.
