public enum Reception
extends java.lang.Enum<Reception>

Distinguishes conditional observer methods from observer methods which are always notified.

A conditional observer method is an observer method which is notified of an event only if an instance of the bean that defines the observer method already exists in the current context.

Beans with scope @Dependent may not have conditional observer methods.
