Instance Method Details

#_rooted_doc_key(value) ⇒ Object

Note:

this method was introduced with CollectionModel. The individual elements/items wouldn't know how to fetch their own model via their parent. This required to introduce _rooted_doc_key in all DoubleModel ancestors. It just delegates up the resolution of a value key.

Note:

this method can't be protected. It might be accessed by cousing classes. parent class to a child class. See last line of this method.

Offers a method for child classes to transform the key, provided that the child's doc can be accessed.

Parameters:

  • value (Content::DoubleModel, Array<String>, String) —
    • String or Array<String>: is mirrored.
    • DoubleModel and root?: is mirrored.
    • non root? DoubleModel: deletages to _parent
