63 | =head1 NAME | |||
64 | ||||
65 | Moose::Meta::Method::Augmented - A Moose Method metaclass for augmented methods | |||
66 | ||||
67 | =head1 DESCRIPTION | |||
68 | ||||
69 | This class implements method augmentation logic for the L<Moose> | |||
70 | C<augment> keyword. | |||
71 | ||||
72 | The augmentation subroutine reference will be invoked explicitly using | |||
73 | the C<inner> keyword from the parent class's method definition. | |||
74 | ||||
75 | =head1 INHERITANCE | |||
76 | ||||
77 | C<Moose::Meta::Method::Augmented> is a subclass of L<Moose::Meta::Method>. | |||
78 | ||||
79 | =head1 METHODS | |||
80 | ||||
81 | =over 4 | |||
82 | ||||
83 | =item B<< Moose::Meta::Method::Augmented->new(%options) >> | |||
84 | ||||
85 | This constructs a new object. It accepts the following options: | |||
86 | ||||
87 | =over 8 | |||
88 | ||||
89 | =item * class | |||
90 | ||||
91 | The metaclass object for the class in which the augmentation is being | |||
92 | declared. This option is required. | |||
93 | ||||
94 | =item * name | |||
95 | ||||
96 | The name of the method which we are augmenting. This method must exist | |||
97 | in one of the class's superclasses. This option is required. | |||
98 | ||||
99 | =item * method | |||
100 | ||||
101 | The subroutine reference which implements the augmentation. This | |||
102 | option is required. | |||
