Class ScopedValuesExamples

java.lang.Object

net.jrodolfo.java_evolution.java25.ScopedValuesExamples

public class ScopedValuesExamples
extends Object

Demonstrates scoped values, finalized in Java 25 by JEP 506.

Scoped values solve a common context-passing problem. Data such as a user, request ID, or tenant often needs to be available through a call chain without adding parameters everywhere. Compared with mutable thread-local state, scoped values bind immutable data to a bounded dynamic scope, making cleanup and ownership easier to reason about.
