Annotation Type DeepImmutable

@Retention(CLASS)
@Target(TYPE)
@Documented
public @interface DeepImmutable

A class is considered DeepImmutable when:

• All fields are final and cannot be reassigned
• All objects reachable from the instance are immutable (the entire object graph is immutable)
• No mutable internal state is exposed

Classes annotated with DeepImmutable are thread-safe, provided they are safely constructed (the this reference does not escape during construction) and do not expose mutable state.

This annotation is for documentation purposes only and does not enforce or verify immutability.

Since:

4.1.0
