NAME

Venus::Space - Space Class

ABSTRACT

Space Class for Perl 5

SYNOPSIS

package main;

use Venus::Space;

my $space = Venus::Space->new('foo/bar');

# $space->package; # Foo::Bar

DESCRIPTION

This package provides methods for parsing and manipulating package namespaces.

INHERITS

This package inherits behaviors from:

Venus::Name

METHODS

This package provides the following methods:

all

all(Str $method, Any @args) (ArrayRef[Tuple[Str, Any]])

The all method executes any available method on the instance and all instances representing packages inherited by the package represented by the invocant. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.

Since 0.01

all example 1

package main;

use Venus::Space;

my $space = Venus::Space->new('Venus');

my $all = $space->all('id');

# [["Venus", "Venus"]]

all example 2

package main;

use Venus::Space;

my $space = Venus::Space->new('Venus/Space');

my $all = $space->all('inherits');

# [
#   [
#     "Venus::Space", ["Venus::Name"]
#   ],
#   [
