Instance Method Details

#instantiate_with_text_elements(parent, text_elements) ⇒ Object

This initializer can take an XML::Node and scrape out any text elements with the names given in the “text_elements” array. Each element found underneath “parent” with a name in “text_elements” causes an attribute to be initialized on the instance. This means you don’t have to pick out individual text elements in each initializer of each class (Route, TrackPoint, Track, etc). Just pass an array of possible attributes to this method.
