/**
* 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 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 {
*
* 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();
* }
*
* void debug(AccessibleObject ao, Object this, Object value) {
* ...
* }
* }
* </pre>
