Instance Method Details

#call(obj) ⇒ Object

Given an Array-like or Hash-like object, returns a similar object with keys coerced according to the target MapWithIndifferentAccess::Normalization::DeepNormalizer's strategy. Given an object that is not Array-like or Hash-like, then the given object is returned.

During this process, any hash entry values or array items that are instances of Map or List are replaced with Hash or Array deconstructions respectively. If a Map or List is given, then the same type of object is returned.

If a Hash or an object that resonds to #to_hash and #each_pair is given, then a Hash is returned. The same applies to each Hash/Map entry value or Array/List item that is traversed.

If an Array or an object that resonds to #to_ary is given, then an Array is returned. The same applies to each Hash/Map entry value or Array/List item that is traversed.

If any keys, Hash entry values, or Array items are replaced, then a new object is returned that includes those replacements. Otherwise, the given object is returned. In either case, the contents of obj are not modified.
