Class EntityRetentionGraph

java.lang.Object
org.onebusaway.gtfs_transformer.factory.EntityRetentionGraph
public class EntityRetentionGraph extends Object
We have the concept of retaining up and retaining down. Retain up: retain things that depend on the target object Retain down: retain things that the target object depends on Usually, we start by retaining some object, which starts as series of "retain up" operations to grab everything that depends on that object. As each object is retained up, it typically at this point also starts a subsequent chain of retain down operations, so that the dependencies of that object are retained as well.
