#item ⇒ Object

Return single item response as a Hash

Some DynamoDB operations, such as ‘GetItem`, will only return a single ’Item’ entry. This converts that entry in a Hash where values have been type-casted into their Ruby equivalents.

def item
  return unless data["Item"]
  @item ||= DynamoDB.deserialize(data["Item"])
end

#items ⇒ Object

Return an Array of item responses

DynamoDB operations like ‘Query` return a collection of entries under the ’Items’ key. This returns an Array of Hashes where values have been casted to their Ruby equivalents.
