org.opensaml.util.storage.ReplayCache

public class ReplayCache
extends Object

Class that uses an underlying StorageService to track information associated with messages in order to detect message replays. This class is thread-safe and uses a basic reentrant lock to avoid corruption of the underlying store, as well as to prevent race conditions with respect to replay checking.
