NAME

       Class::MakeMethods::Emulator::accessors - Emulate the accessors module

SYNOPSIS

	 package Foo;
	 use Class::MakeMethods::Emulator::accessors qw( foo bar baz );

	 my $obj = bless {}, 'Foo';

	 # generates chaining accessors:
	 $obj->foo( 'hello ' )
	     ->bar( 'world' )
	     ->baz( "!
" );

	 print $obj->foo, $obj->bar, $obj->baz;

       This module also defines subpackages for the classic and chaining subclasses:

	 package Bar;
	 use Class::MakeMethods::Emulator::accessors;
	 use Class::MakeMethods::Emulator::accessors::classic qw( foo bar baz );

	 my $obj = bless {}, 'Bar';

	 # always return the current value, even on set:
	 $obj->foo( 'hello ' ) if $obj->bar( 'world' );

	 print $obj->foo, $obj->bar, $obj->baz( "!
" );

DESCRIPTION

       This module emulates the functionality of the accessors module, using Class::MakeMethods to generate similar methods.

       In particular, the following lines are equivalent:

	 use accessors 'foo';
	 use Class::MakeMethods::Template::Hash 'scalar --get_set_chain' => 'foo';

	 use accessors::chained 'foo';
	 use Class::MakeMethods::Template::Hash 'scalar --get_set_chain' => 'foo';

	 use accessors::classic 'foo';
	 use Class::MakeMethods::Template::Hash 'scalar' => 'foo';

       You may use this module directly, as shown in the SYNOPSIS above,

       Furthermore, you may call "use Class::MakeMethods::Emulator::accessors '-take_namespace';" to alias the accessors namespace to this
       package, and subsequent calls to the original package will be transparently handled by this emulator. To remove the emulation aliasing,
       call "use Class::MakeMethods::Emulator::accessors '-release_namespace'".  The same mechanism is also available for the classic and chained
       subclasses.

       Caution: This affects all subsequent uses of the accessors module in your program, including those in other modules, and might cause
       unexpected effects.

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::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.
