 * ThreadSafe
 * 
 * The class to which this annotation is applied is thread-safe. This means that
 * no sequences of accesses (reads and writes to public fields, calls to public
 * methods) may put the object into an invalid state, regardless of the
 * interleaving of those actions by the runtime, and without requiring any
 * additional synchronization or coordination on the part of the caller.
