Annotation Type 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

• ReentrantLock, or
• ReadWriteLock

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.
