NAME

       Class::MakeMethods::Template::Ref - Universal copy and compare methods

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Template::Ref (
	   'Hash:new'	   => [ 'new' ],
	   clone	   => [ 'clone' ]
	 );

	 package main;

	 my $obj = MyObject->new( foo => ["Foozle", "Bozzle"] );
	 my $clone = $obj->clone();
	 print $obj->{'foo'}[1];

DESCRIPTION

       The following types of methods are provided via the Class::MakeMethods interface:

   clone
       Produce a deep copy of an instance of almost any underlying datatype.

       Parameters:

       init_method

       If defined, this method is called on the new object with any arguments passed in.

   prototype
       Create new instances by making a deep copy of a static prototypical instance.

       Parameters:

       init_method

       If defined, this method is called on the new object with any arguments passed in.

   compare
       Compare one object to another.

       Templates

       o   default

	   Three-way (sorting-style) comparison.

       o   equals

	   Are these two objects equivalent?

       o   identity

	   Are these two references to the exact same object?

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.
