103 | Class::MOP::Method - Method Meta Object |
104 | |
8b978dd5 |
105 | =head1 DESCRIPTION |
106 | |
32202ce2 |
107 | The Method Protocol is very small, since methods in Perl 5 are just |
108 | subroutines within the particular package. We provide a very basic |
86482605 |
109 | introspection interface. |

118 | |

119 | This will return a B<Class::MOP::Class> instance which is related |

120 | to this class. |

127d39a7 |
129 | |
32202ce2 |
130 | This is the basic constructor, it returns a B<Class::MOP::Method> |
131 | instance which wraps the given C<$code> reference. You can also |
4c105333 |
132 | set the C<package_name> and C<name> attributes using the C<%params>. |
32202ce2 |
133 | If these are not set, then thier accessors will attempt to figure |
4c105333 |
134 | it out using the C<Class::MOP::get_code_info> function. |
135 | |
136 | =item B<clone (%params)> |
137 | |
32202ce2 |
138 | This will make a copy of the object, allowing you to override |
4c105333 |
139 | any values by stuffing them in C<%params>. |
