10  * A container implementation that adds monitoring support
11  * for constructors and methods registered using
12  * registerConstructor(), registerStaticMethod() and registerMethod().
13  * </p>
14  * <p>
15  * Components registered with registerComponent() are not automatically
16  * monitored.
17  * </p>
18  * <p>
19  * Only components directly registerd with the registerConstructor(),
20  * registerMethod(), registerStaticMethod() are monitored.
21  * Parameters of the components are not monitored.<br>
22  * Use {@link Monitors} to add monitoring support.
