NAME

Class::MakeMethods::Emulator::Struct - Emulate Class::Struct

SYNOPSIS

  use Class::MakeMethods::Emulator::Struct; 
  
  struct ( 
      simple  => '$',
      ordered => '@', 
      mapping => '%',
      obj_ref => 'FooObject' 
  );

DESCRIPTION

This module emulates the functionality of Class::Struct by munging the provided field-declaration arguments to match those expected by Class::MakeMethods.

It supports the same four types of accessors, the choice of array-based or hash-based objects, and the choice of installing methods in the current package or a specified target.

EXAMPLE

The below three declarations create equivalent methods for a simple hash-based class with a constructor and four accessors.

  use Class::Struct;
  struct ( 
      simple  => '$',
      ordered => '@', 
      mapping => '%',
      obj_ref => 'FooObject' 
  );
  
  use Class::MakeMethods::Emulator::Struct; 
  struct ( 
      simple  => '$',
      ordered => '@', 
      mapping => '%',
      obj_ref => 'FooObject' 
    );
  
  use Class::MakeMethods ( 
      -MakerClass               => 'Standard::Array',
      'new'                     => 'new',
      'scalar'                  => 'simple',
      'array -auto_init 1'      => 'ordered', 
      'hash -auto_init 1'       => 'mapping',
      'object -auto_init 1'     => '-class FooObject obj_ref' 
    );

COMPATIBILITY

This module aims to offer a "95% compatible" drop-in replacement for the core Class::Struct module for purposes of comparison and code migration.

The class-struct.t test for the core Class::Struct module is included with this package. The test is unchanged except for the a direct substitution of this emulator's name in the place of the core module.

However, there are numerous internal differences between the methods generated by the original Class::Struct and this emulator, and some existing code may not work correctly without modification.
