Constructor Details

#initialize(keys, row) ⇒ Row

The instance is created with an array of strings or symbols used to denote the keys of the model. The keys MUST be specified in the order of the data elements in the data array. When the model is asked for the value for a given key, the value is retrieved from the data array by the position of the key in the keys array.
