92 Mouse::Meta::Class - hook into the Mouse MOP
96 =head2 initialize ClassName -> Mouse::Meta::Class
98 Finds or creates a Mouse::Meta::Class instance for the given ClassName. Only
99 one instance should exist for a given class.
101 =head2 new %args -> Mouse::Meta::Class
103 Creates a new Mouse::Meta::Class. Don't call this directly.
105 =head2 name -> ClassName
107 Returns the name of the owner class.
109 =head2 superclasses -> [ClassName]
111 Gets (or sets) the list of superclasses of the owner class.
113 =head2 add_attribute Mouse::Meta::Attribute
115 Begins keeping track of the existing L<Mouse::Meta::Attribute> for the owner
118 =head2 compute_all_applicable_attributes -> (Mouse::Meta::Attribute)
120 Returns the list of all L<Mouse::Meta::Attribute> instances associated with
121 this class and its superclasses.
123 =head2 get_attribute_map -> { name => Mouse::Meta::Attribute }
125 Returns a mapping of attribute names to their corresponding
126 L<Mouse::Meta::Attribute> objects.
128 =head2 has_attribute Name -> Boool
130 Returns whether we have a L<Mouse::Meta::Attribute> with the given name.
132 =head2 get_attribute Name -> Mouse::Meta::Attribute | undef
134 Returns the L<Mouse::Meta::Attribute> with the given name.
136 =head2 linearized_isa -> [ClassNames]
138 Returns the list of classes in method dispatch order, with duplicates removed.
