Annotation Interface ThreadSafe

@Documented @Retention(RUNTIME) public @interface ThreadSafe
Classes, fields, or methods annotated @ThreadSafe are safe to use in multithreading contexts. In general, classes that adhere to (one of) the following concepts:
  • Statelessness: no methods relies on external state or maintain state at all,
  • Immutability: all attributes are final so that internal state can't be modified at all,
  • Thread locality: non-final fields are only accessed via an independently initialized copy,
  • Atomicity: all operations on fields are perform via atomic data types, or
  • Synchronization: all non-final methods, fields, or method local variables are manipulated via locks, that is, in a synchronized manner
are safe to use from multiple threads. In addition, thread-safety can be achieved by using the concepts of either in which a thread acquires the lock for write operations and protects the locked object or data element from changes until the lock is released.
