NAME

Venus::Role::Boxable - Boxable Role

ABSTRACT

Boxable Role for Perl 5

SYNOPSIS

package Example;

use Venus::Class;

with 'Venus::Role::Boxable';

attr 'text';

package main;

my $example = Example->new(text => 'hello, world');

# $example->box('text')->lc->ucfirst->concat('.')->unbox->get;

# "Hello, world."

DESCRIPTION

This package modifies the consuming package and provides a method for boxing itself. This makes it possible to chain method calls across objects and values.

METHODS

This package provides the following methods:

box

box(string | coderef $method, any @args) (object)

The box method returns the invocant boxed, i.e. encapsulated, using Venus::Box. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.
