- All Implemented Interfaces:
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
@Dependentmay not have conditional observer methods.
All Methods Static Methods Concrete Methods Modifier and Type Method Description

values()Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail
public static final Reception IF_EXISTS
Specifies that an observer method is only called if the current instance of the bean declaring the observer method already exists.
If there is no active context for the scope to which the bean declaring this observer method belongs, then the observer method is not called.
public static final Reception ALWAYSSpecifies that an observer method always receives event notifications.
public static Reception values()Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (Reception c : Reception.values()) System.out.println(c);
- an array containing the constants of this enum type, in the order they are declared
public static Reception valueOf(java.lang.String name)Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
name- the name of the enum constant to be returned.
- the enum constant with the specified name
java.lang.IllegalArgumentException- if this enum type has no constant with the specified name
java.lang.NullPointerException- if the argument is null
