Instance Method Details

#__redefine_enumerable_methods(h) ⇒ Object

Fix the problem of Hashie::Mash returning unexpected values for ‘min` and `max` methods

People can define names for aggregations such as ‘min` and `max`, but these methods are defined in `Enumerable#min` and `Enumerable#max`

{ foo: 'bar' }.min
# => [:foo, "bar"]

Therefore, any Hashie::Mash instance value has the ‘min` and `max` methods redefined to return the real value
