Field Detail

LOG

public static final org.slf4j.Logger LOG

EMPTY_INT_ARRAY

public static final int[] EMPTY_INT_ARRAY

we use empty int arrays for various things, e.g. transfers from isolated stops. They're immutable so only use one

nStops

public final int nStops

nPatterns

public final int nPatterns

nTargets

public final int nTargets

The number of targets (vertices or samples)

transfersForStop

public final List<int[]> transfersForStop

For every stop, one pair of ints (targetStopIndex, distanceMeters) for each transfer out of that stop. This uses 0-based stop indices that are specific to RaptorData

patternsForStop

public final List<int[]> patternsForStop

A list of pattern indexes passing through each stop, again using Raptor indices.

timetablesForPattern

public List<RaptorWorkerTimetable> timetablesForPattern

For each pattern, a 2D array of stoptimes for each trip on the pattern.

hasSchedules

public boolean hasSchedules

does this RaptorData have any scheduled trips?

hasFrequencies

public boolean hasFrequencies

does this RaptorData have any frequency trips?

addedStops

public gnu.trove.map.TObjectIntMap<AddTripPattern.TemporaryStop> addedStops

Map from stops that do not exist in the graph but only for the duration of this search to their stop indices in the RAPTOR data.

transferRules

public gnu.trove.map.TIntObjectMap<List<TransferRule>> transferRules

Some stops may have special transfer rules. They are stored here.

baseTransferRules

public List<TransferRule> baseTransferRules

The transfer rules to be applied in the absence of another transfer rule

boardingAssumption

public RaptorWorkerTimetable.BoardingAssumption boardingAssumption

The boarding assumption used for initial vehicle boarding, and for when there is no transfer rule defined

targetsForStop

public final List<int[]> targetsForStop

For each stop, one pair of ints (targetID, distanceMeters) for each destination near that stop. For generic TimeSurfaces these are street intersections. They could be anything though since the worker doesn't care what the IDs stand for. For example, they could be point indexes in a pointset.

indexForStop

public final transient gnu.trove.map.TIntIntMap indexForStop

The 0-based RAPTOR indices of each stop from their vertex IDs

stopNames

public final transient List<String> stopNames

Optional debug data: the name of each stop.

patternNames

public final transient List<String> patternNames

RaptorWorkerData

public RaptorWorkerData(Graph graph,

                        ProfileRequest request,
                        TaskStatistics ts)

Create RaptorWorkerData for the given window and graph

Create RaptorWorkerData to be used to build ResultSets directly without creating an intermediate SampleSet

RaptorWorkerData

public RaptorWorkerData(TransitLayer transitLayer,
                        LinkedPointSet targets,
                        org.joda.time.LocalDate date)

This is an adapter constructor, which makes Analyst cluster worker data from a new-style TransportNetwork. RaptorWorkers are (intentionally) very similar to the TransitLayer of TransportNetworks. For now we'll just perform a copy, filtering out any unused patterns and trips. TODO study the differences between the two, and merge the two data structures into one class.

findStopsNear

public gnu.trove.map.TIntIntMap findStopsNear(ShortestPathTree spt,
                                              Graph graph,
                                              boolean useTimes,
                                              float walkSpeed)

find stops from a given SPT, including temporary stops. If useTimes is true, use times from the SPT, otherwise use distances
