org.onebusaway.transit_data_federation.services.blocks.FrequencyBlockTripIndex
A FrequencyBlockTripIndex is a collection of {@link BlockTripEntry} elementsthat have the following properties in common: 1) Each {@link BlockTripEntry} refers to the same stop sequence pattern andunderlying shape of travel. 2) Each {@link BlockTripEntry} has the same set of service ids (see{@link BlockConfigurationEntry#getServiceIds()}3) Each {@link BlockTripEntry} refers to a frequency-based trip with a{@link FrequencyEntry}. Since the same {@link BlockTripEntry} can havemultiple {@link FrequencyEntry}, a trip may appear more than once in the index. 4) The list of {@link FrequencyEntry} elements is sorted by start time and nofrequency block ever overtakes another block. 4) The {@link ServiceIntervalBlock} additionally captures the min and maxarrival and departure times for each trip in the list, in the same sorted order as the block list. These assumptions allow us to do efficient searches for blocks that are active at a particular time. @author bdferris @see BlockCalendarService
