Class EntryIdAndCallback<K,T>

java.lang.Object
  org.onebusaway.transit_data_federation.services.serialization.EntryIdAndCallback<K,T>

Type Parameters:

K - the id type

T - the callback result type

public class EntryIdAndCallback<K,T>
extends Object

A sort of delayed-binding mechanism to help with serializing large, highly connected graphs of Java objects where you usually get a stack-depth exception when the default DFS Java serialization mechanism does its thing. This support class is to help where you replace your object references with id references in a custom object serialization routine. Then you also have a callback that repopulates the actual object reference upon deserialization.
