NAME

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

CONTENTS

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( "!\n" );
 
  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( "!\n" );



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.

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

SEE ALSO

See Class::MakeMethods for general information about this distribution.

See Class::MakeMethods::Emulator for more about this family of subclasses.

See accessors for documentation of the original module.
