org.symphonyoss.s2.common.legacy.id.LegacyIdFactory

public class LegacyIdFactory
extends java.lang.Object

A factory to create inferred Hash values each of which is a 2.0 ID which acts as a mirror for an object in the legacy (Symphony1.5) space. Many methods take a podId which it uses to generate a globally unique ID for each object across all pods. This means that if the same threadId happens to exist in 2 separate pods and we create a 2.0 Sequence to represent those two threads that the 2.0 IDs will not collide in a multi tenant environment. Note that where we refer to userId in this class that we expect the "external" userId which already includes the podId and is already globally unique. In this case the podId is not included again.
