Instance Method Details
#find(handle, connection = nil) ⇒ Object
Finds a specific entity in iTunes U. To find an entity you will need to know both its type (Course, Group, etc) and handle. Handles uniquely identify entities in iTunes U and the entity type is used to search the returned XML for the specific entity you are looking for. For example, Course.find(123456, rtunes_connection_object)
