Examples with FareComponent org.opentripplanner.routing.core.FareComponent used on opensource projects

Example 1 with FareComponent

use of org.opentripplanner.routing.core.FareComponent in project OpenTripPlanner by opentripplanner.

the class DefaultFareServiceImpl method populateFare.

/**
 * Builds the Fare object for the given currency, fareType and fareRules.
 * <p>
 * Besides calculating the lowest fare, we also break down the fare and which routes
 * correspond to which components. Note that even if we cannot get a lowest fare
 * (if some rides don't have fare rules), there will still be a breakdown for those
 * parts which have fares.
 * <p>
 * As an example, given the rides A-B and B-C. Where A-B and B-C have fares of 10
 * each, 2 fare detail objects are added, one with fare 10 for A-B and one with fare 10
 * for B-C.
 * <p>
 * If we add the rule for A-C with a fare of 15, we will get 1 fare detail object
 * with fare 15, which lists both A-B and B-C as routes involved.
 * <p>
 * If our only rule were A-B with a fare of 10, we would have no lowest fare, but
 * we will still have one fare detail with fare 10 for the route A-B. B-C will not
 * just not be listed at all.
