79 | Class::MOP::Module - Module Meta Object |
80 | |
2243a22b |
81 | =head1 DESCRIPTION |
82 | |
1f44239e |
83 | A module is essentially a L<Class::MOP::Package> with metadata, in our |
84 | case the version and authority. |

86 | =head1 INHERITANCE |
87 | |
1f44239e |
88 | B<Class::MOP::Module> is a subclass of L<Class::MOP::Package>. |

1f44239e |
94 | =item B<< $metamodule->version >> |
2243a22b |
95 | |
1f44239e |
96 | This is a read-only attribute which returns the C<$VERSION> of the |
97 | package, if one exists. |
127d39a7 |
98 | |
1f44239e |
99 | =item B<< $metamodule->authority >> |
127d39a7 |
100 | |
1f44239e |
101 | This is a read-only attribute which returns the C<$AUTHORITY> of the |
102 | package, if one exists. |
127d39a7 |
103 | |
1f44239e |
104 | =item B<< $metamodule->identifier >> |
7f436b8c |
105 | |
1f44239e |
106 | This constructs a string which combines the name, version and |
107 | authority. |

110 | |
1f44239e |
111 | This will return a L<Class::MOP::Class> instance for this class. |
