public class RewindableInputStream
extends DynamicPushbackInputStream

RewindableInputStream is a specialization of the PushbackInputStream that maintains an internal buffer of read bytes that a user can rewind (unread) back into the stream without having to do their own buffer management. The rewind buffer grows dynamically
