=head1 NAME
Class::MakeMethods::Emulator::accessors - Emulate the accessors module
=head1 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" );
=head1 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 C<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
C<use Class::MakeMethods::Emulator::accessors '-release_namespace'>.
The same mechanism is also available for the classic and chained subclasses.
B<Caution:> This affects B<all> subsequent uses of the accessors module in
your program, including those in other modules, and might cause
unexpected effects.
=head1 SEE ALSO
See L<Class::MakeMethods> for general information about this distribution.
See L<Class::MakeMethods::Emulator> for more about this family of subclasses.
See L<accessors> for documentation of the original module.
