.annotate(o) ⇒ Annotation<self>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Finds an existing annotation for the given object and returns it. If no annotation was found, and a block is given, a new annotation is created from the initializer hash that must be returned from the block. If no annotation was found and no block is given, this method returns ‘nil`

  end

.annotate_new(o, init_hash) ⇒ Annotation<self>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Forces the creation or removal of an annotation of this type. If ‘init_hash` is a hash, a new annotation is created and returned If `init_hash` is `nil`, then the annotation is cleared and the previous annotation is returned.

.register_ptype(loader, ir) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Register the Annotation type. This is the type that all custom Annotations will inherit from.

.type_name ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Uses name of type instead of name of the class (the class is likely dynamically generated and as such, has no name)
