| * Marks a method as having a specific kind of {@link ExchangePattern} for use with |
| * <a href="http://camel.apache.org/bean-integration.html">Bean Integration</a> or |
| * <a href="http://camel.apache.org/spring-remoting.html">Spring Remoting</a> |
| * to overload the default value which is {@link ExchangePattern#InOut} for request/reply if no annotations are used. |
| * |
| * There are abbreviation annotations like {@link InOnly} or {@link InOut} which are typically used for |
| * the common message exchange patterns. You could also add this annotation onto your own custom annotation to default |
| * the message exchange pattern when your own annotation is added to a method |
| * <a href="using-exchange-pattern-annotations.html">as in this example</a>. |
| * |
| * This annotation can be added to individual methods or added to a class or interface to act as a default for all methods |
| * within the class or interface. |
| * |
| * See the <a href="using-exchange-pattern-annotations.html">using exchange pattern annotations</a> |
| * for more details on how the overloading rules work. |
