restore

public ThreadInfoSet restore(ThreadInfoSet inSitu)

Description copied from interface: Memento

note that there is no guarantee the restored object will be the same that is (optionally) passed in. Implementations are free to restore in-situ or create a new object if a non-null reference is provided. Callers are responsible for identity integrity if they do provide in-situ objects The caller does not guarantee the provided in-situ object was the one the Memento was created from
