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.
