NAME

       Class::MakeMethods::Attribute - Declare generated subs with attribute syntax

SYNOPSIS

	 package MyObject;
	 use Class::MakeMethods::Attribute 'Standard::Hash';

	 sub new    :MakeMethod('new');
	 sub foo    :MakeMethod('scalar');
	 sub bar    :MakeMethod('scalar', { hashkey => 'bar_data' });
	 sub debug  :MakeMethod('Standard::Global:scalar');

DESCRIPTION

       This package allows common types of methods to be generated via a subroutine attribute declaration. (Available in Perl 5.6 and later.)

       Adding the :MakeMethod() attribute to a subroutine declaration causes Class::MakeMethods to create and install a subroutine based on the
       parameters given to the :MakeMethod attribute.

       You can declare a default method-generation class by passing the name of a MakeMethods subclass in the use Class::MakeMethods::Attribute
       statement. This default method-generation class will also apply as the default to any subclasses declared at compile time. If no default
       method-generation class is selected, you will need to fully-qualify all method type declarations.

EXAMPLE

       Here's a typical use of Class::MakeMethods::Attribute:

	 package MyObject;
	 use Class::MakeMethods::Attribute 'Standard::Hash';

	 sub new    :MakeMethod('new');
	 sub foo    :MakeMethod('scalar');
	 sub bar    :MakeMethod('scalar', { hashkey => 'bar_data' });
	 sub debug  :MakeMethod('Standard::Global:scalar');

	 package MySubclass;
	 use base 'MyObject';

	 sub bazzle :MakeMethod('scalar');

       This is equivalent to the following explicit Class::MakeMethods invocations:

	 package MyObject;

	 use Class::MakeMethods (
	   -MakerClass => 'Standard::Hash',
	   new => 'new',
	   scalar => 'foo',
	   scalar => [ 'ba', { hashkey => 'bar_data' } ],
	   'Standard::Global:scalar' => 'debug',
	 );

	 package MySubclass;
	 use base 'MyObject';

	 use Class::MakeMethods (
	   -MakerClass => 'Standard::Hash',
	   scalar => 'bazzle',
	 );

DIAGNOSTICS

       The following warnings and errors may be produced when using Class::MakeMethods::Attribute to generate methods. (Note that this list does
       not include run-time messages produced by calling the generated methods, or the standard messages produced by Class::MakeMethods.)

       Can't apply MakeMethod attribute to %s declaration.
	   You can not use the ":MakeMethod" attribute with lexical or anonymous subroutine declarations.

       No method type provided for MakeMethod attribute.
	   You called ":MakeMethod()" without the required method-type argument.

NAME

       Class::MakeMethods::Emulator - Demonstrate class-generator equivalency

SYNOPSIS

	 # Equivalent to use Class::Singleton;
	 use Class::MakeMethods::Emulator::Singleton;

	 # Equivalent to use Class::Struct;
	 use Class::MakeMethods::Emulator::Struct;
	 struct ( ... );

	 # Equivalent to use Class::MethodMaker( ... );
	 use Class::MakeMethods::Emulator::MethodMaker( ... );

	 # Equivalent to use base 'Class::Inheritable';
	 use base 'Class::MakeMethods::Emulator::Inheritable';
	 MyClass->mk_classdata( ... );

	 # Equivalent to use base 'Class::AccessorFast';
	 use base 'Class::MakeMethods::Emulator::AccessorFast';
	 MyClass->mk_accessors(qw(this that whatever));

	 # Equivalent to use accessors( ... );
	 use Class::MakeMethods::Emulator::accessors( ... );

	 # Equivalent to use mcoder( ... );
	 use Class::MakeMethods::Emulator::mcoder( ... );

DESCRIPTION

       In several cases, Class::MakeMethods provides functionality closely equivalent to that of an existing module, and it is simple to map the
       existing module's interface to that of Class::MakeMethods.

       Class::MakeMethods::Emulator provides emulators for Class::MethodMaker, Class::Accessor::Fast, Class::Data::Inheritable, Class::Singleton,
       Class::Struct, accessors, and mcoder, each of which passes the original module's test suite, usually requiring only the addition of a a
       single line to each test, activating the emulation module.

       Beyond demonstrating compatibility, these emulators also generally indicate the changes needed to switch to direct use of
       Class::MakeMethods functionality, illustrate commonalities between the various modules, and serve as a source for new ideas that can be
       integrated into Class::MakeMethods.
