57 <h3>Interception Factory Introduction</h3>
58
59 <p>CDI 2.0 introduces the <code>javax.enterprise.inject.spi.InterceptionFactory<T> </code> interface,
60 which allows to create a wrapper instance whose method invocations are intercepted by method
61 interceptors and forwarded to a provided instance. </p>
62 <p>An InterceptionFactory can be obtained by calling <code>BeanManager.createInterceptionFactory()</code> as
63 defined in Obtain an InterceptionFactory.</p>
64
65 <h3>Description of the Example</h3>
66 <p>This example demonstrates a producer method definition using <code>InterceptionFactory</code>. The
67 produced bean instance will be a wrapper of <code>MyGreetingImpl</code> with single interceptor associated by
68 <code>HelloAdder</code>. First please enter a name, then click the <strong>Submit</strong> button. A complete
69 message including your input and the wrapped message will be displayed.
70 </p>
