NAME

JIP::Object - A simple object system.

VERSION

This document describes JIP::Object version 0.031.

SYNOPSIS

    use JIP::Object;

    my $obj = JIP::Object->new;

    $obj->has('foo', (get => '+', set => '+'));
    $obj->set_foo(42)->foo; # 42

    $obj->method('say_foo', sub {
        my $self = shift;
        print $self->foo, "\n";
    });
    $obj->say_foo;

Inheritance with the prototype chain:

    my $proto = JIP::Object->new;

    # Creates an own method 'as_string' on $proto
    $proto->method('as_string', sub { 'prototype' });

    my $obj = JIP::Object->new(proto => $proto);

    ref $obj->own_method('as_string'); # q{}
    $obj->as_string;                   # q{prototype}

    # Creates an own method 'as_string' on $obj
    $obj->method('as_string', sub { 'object' });

    # If the method is found in $obj, then proto is not checked.
    ref $obj->own_method('as_string'); # q{CODE}
    $obj->as_string;                   # q{object}

    # The end of the prototype chain as undef.
    ref $obj->proto->proto; # q{}

METHODS

new

Construct a new JIP::Object object.

    my $obj = JIP::Object->new;
    my $obj = JIP::Object->new(proto => JIP::Object->new);;

has

Define a new property.

    # Public
    $obj->has('foo', (get => '+', set => '+'));
    $obj->set_foo(42)->foo; # 42

    # Private
    $obj->has('bar', (get => '-', set => '-'));
    $obj->_set_bar(42)->_bar; # 42

    # Create user-defined names for getters/setters
    $obj->has('wtf' => (get => 'wtf_getter', set => 'wtf_setter'));
    $obj->wtf_setter(42)->wtf_getter; # 42

    # Pass an optional first argument of setter to set
    # a default value, it should be a constant or callback.
    $obj->has('baz' => (get => '+', set => '+', default => 42));
    ($self->set_baz->baz; # 42

    $obj->has('qux' => (get => '+', set => '+', default => sub {
        my $self = shift;
        return $self->baz;
    }));
    $self->set_qux->qux; # 42

    # Declaring multiple attributes in a single declaration
    $obj->has([qw(one two three)]);

method

Define a new method.

    $obj = $obj->method('get_x', sub {
        my $self = shift;
        return $self->x;
    });

proto

Returns the value of the 'proto' attribute.

    $obj->proto;

set_proto

Sets the value of the 'proto' attribute.

    $obj->set_proto($proto);

own_method

    $code = $obj->own_method('string value of a method name');

The own_method returns CODE if object has a method of the specified name, undef if it does not.
