s%Object with arbitrary attributes which may be added to a schedule.

151

152

This class should be used as the base class for GTFS objects which may

153

be stored in a Schedule. It defines some methods for reading and writing

154

attributes. If self._schedule is None than the object is not in a Schedule.

155

156

Subclasses must:

157

* define an __init__ method which sets the _schedule member to None or a

158

weakref to a Schedule

159

* Set the _TABLE_NAME class variable to a name such as 'stops', 'agency', ...

160

* define methods to validate objects of that type

161

162

163

This method is only called when name is not found in __dict__.

Callers may assign arbitrary values to instance attributes.

172

Stop.ParseAttributes validates attributes according to GTFS and converts some

173

into native types. ParseAttributes may delete invalid attributes.

174

Accessing an attribute that is a column in GTFS will return None if this

175

object does not have a value or it is ''.

176

A Stop object acts like a dict with string values.

177

178

Attributes:

179

stop_lat: a float representing the latitude of the stop

180

stop_lon: a float representing the longitude of the stop

181

All other attributes are strings.
