NAME
Object::Prototype - Prototypal Object Model a la Javascript
SYNOPSIS
use Object::Prototype;
use What::Ever;
my $classical = What::Ever->new();
$classical->foo("bar");
is $classical->foo, "bar";
my $prototypal = Object::Prototype->new();
$prototypal->foo # bar, of course;
$prototypal->prototype( baz => sub { shift->foo . shift->bar });
$prototypal->baz() # foobar
$classical->baz() # croaks
DESCRIPTION
Object::Prototype implements JavaScript-like prototypal object system.
If you are familiar with JavaScript's object system, you should have no
problem using this module. If you are not, please read
.
There is one advantage over JavaScript, however. As the example above,
you can start with conventional, classical, perlish object as the
prototype. To find how it is done, just see the source.
EXPORT
None.
METHODS
new($obj [, \%methods ])
Deeply clones $obj and make it a prototypal object. You can optionally
add methods by passing a hashref like this;
{ method => sub { ... }, method2 => sub { ... } }
Which is a shorthand for
my $p = Object::Prototype->new($obj);
$p->prototype( method => sub { ... } );
$p->prototype( method2 => sub { ... } );
prototype($methname [ => \&code ]);
Accessor/Mutator of the object. You can implement the singleton method
that way.
constructor()
Returns the constructor object. Consider this as prototypal SUPER.
$p->prototype(method => sub{
my $self = shift;
my $retval = $self->constructor->method(@_);
# do whatever to $retval
return $retval
});
