Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(m, *arguments, &block) ⇒ Object

For Array of Hashes returns an array of values of the hash key specified in case doesn't exist an Array method with the same name The keys can be accessed also adding underscore to avoid problems with existent methods examples for the array of hashes ['Peter', city: 'Madrid', 'Lola', city: 'NYC'] : my_array.city my_array._name

#json(*keys) ⇒ Object

In case of an array of json strings will return the keys specified. The keys need to be provided as symbols input: keys: 1 value with key or an array of keys In case the key supplied doesn't exist in the hash then it will be return nil for that one output: if keys given: a hash of (keys, values) or the value, if the key is found more than once in the json string, then it will be return a hash of arrays if no keys given, an empty hash
