Class::MakeMethods::Emulator::accessors - Emulate the accessors module
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" );
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.
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.
