<P>
This interface represents a generic interceptor.
<p>A generic interceptor can intercept runtime events that occur
within a base program. Those events are materialized by (reified
in) joinpoints. Runtime joinpoints can be invocations, field
access, exceptions...
<p>This interface is not used directly. Use the the sub-interfaces
to intercept specific events. For instance, the following class
implements some specific interceptors in order to implement a
debugger:
<pre class=code>
class DebuggingInterceptor implements MethodInterceptor,
ConstructorInterceptor, FieldInterceptor {
Object invoke(MethodInvocation i) throws Throwable {
debug(i.getMethod(), i.getThis(), i.getArgs());
return i.proceed();
}
Object construct(ConstructorInvocation i) throws Throwable {
debug(i.getConstructor(), i.getThis(), i.getArgs());
return i.proceed();
}
Object get(FieldAccess fa) throws Throwable {
debug(fa.getField(), fa.getThis(), null);
return fa.proceed();
}
Object set(FieldAccess fa) throws Throwable {
debug(fa.getField(), fa.getThis(), fa.getValueToSet());
return fa.proceed();
}
void debug(AccessibleObject ao, Object this, Object value) {
...
}
}
