@FunctionalInterface public interface ValueModifier<T extends @Nullable Object> extends Serializable
Receives the current value of a signal for in-place modification. Used with reference signals to apply changes to mutable values while ensuring dependents are properly notified of the change.

This is typically used when you have a mutable object stored in a signal and want to modify it in place rather than replacing it with a new instance.
