Class::MakeMethods::Emulator::accessors3pm

Usage

  package Foo;
  use Class::MakeMethods::Emulator::accessors qw( foo bar baz );
  
  my $obj = bless {}, 'Foo';
  
  # generates chaining accessors:
  $obj->foo( 'hello ' )
      ->bar( 'world' )
      ->baz( "!\n" );
  
  print $obj->foo, $obj->bar, $obj->baz;

  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( "!\n" );

Overview

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.
