public class BlockingInterceptor

extends java.lang.Object

Throws an UnsupportedOperationException. Typically used with an interceptor to prevent specific calls, for instance:

 InterceptionBroker broker = new InterceptionBroker();
 broker.addInterceptor(new BlockingInterceptor("Cannot modify locked JavaBean"), new Signature()
 {
     public boolean matches(Method m)
     {
         return (m.getName().startsWith("set") ? true : false);
     }
 });

 // Create a wrapped, javabean-setter blocked version of foo. Note that foo can
 // still be modified, but unmodifiableFoo cannot have setXxx(...) called
 Foo unmodifiableFoo = (Foo) broker.wrap(foo);
