### "name -\> ClassName"

Returns the name of the owner class.

### "superclasses -\> ClassNames" superclass(ClassNames)

Gets (or sets) the list of superclasses of the owner class.

### "add\_method(name =\> CodeRef)"

Adds a method to the owner class.

### "has\_method(name) -\> Bool"

Returns whether we have a method with the given name.

### "get\_method(name) -\> Mouse::Meta::Method \| undef"

### "get\_all\_attributes -\> (Mouse::Meta::Attribute)"

Returns the list of all Mouse::Meta::Attribute instances associated with this class and its superclasses.

### "linearized\_isa -\> \[ClassNames\]"

Returns the list of classes in method dispatch order, with duplicates removed.

### "new\_object(Parameters) -\> Instance"
