Class TransportNetworkCache

java.lang.Object

org.opentripplanner.transit.TransportNetworkCache

public class TransportNetworkCache
extends Object

This holds one or more TransportNetworks keyed on unique strings. This is a replacement for ClusterGraphBuilder. TODO this should serialize any networks it builds, attempt to reload from disk, and copy serialized networks to S3. Because (de)serialization is now about 2 orders of magnitude faster than building from scratch.
