NAME

Venus::Boolean - Boolean Class

ABSTRACT

Boolean Class for Perl 5

SYNOPSIS

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

# $boolean->negate;

DESCRIPTION

This package provides a representation for boolean values.

INHERITS

This package inherits behaviors from:

Venus::Kind::Value

METHODS

This package provides the following methods:

cast

cast(string $kind) (object | undef)

The cast method converts "value" objects between different "value" object types, based on the name of the type provided. This method will return undef if the invocant is not a Venus::Kind::Value.

Since 0.08

cast example 1

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

my $cast = $boolean->cast('array');

# bless({ value => [0] }, "Venus::Array")

cast example 2

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

my $cast = $boolean->cast('boolean');

# bless({ value => 0 }, "Venus::Boolean")

cast example 3

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

my $cast = $boolean->cast('code');

# bless({ value => sub { ... } }, "Venus::Code")

cast example 4

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

# bless({ value => "0.0" }, "Venus::Float")

cast example 5

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

my $cast = $boolean->cast('hash');

# bless({ value => { "0" => 0 } }, "Venus::Hash")

cast example 6

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;

my $cast = $boolean->cast('number');

cast example 7

package main;

use Venus::Boolean;

my $boolean = Venus::Boolean->new;
