Class ScopedValuesSecondPreviewNotes

java.lang.Object
net.jrodolfo.java_evolution.java22.scoped_values.ScopedValuesSecondPreviewNotes
public class ScopedValuesSecondPreviewNotes extends Object
Explains scoped values as a Java 22 second preview feature.

Scoped values address the same problem as the Java 21 preview: sharing immutable contextual data through a bounded scope without the cleanup hazards of many ThreadLocal designs.

Java 22 kept the API in preview, so this repository keeps the version entry explanatory and points to the final Java 25 scoped-values module for runnable code.
