Interface DynamicMBean

public interface DynamicMBean

The DynamicMBean interface is implemented by resources that expose their definition at runtime. The implementation exposes its attributes, methods and notifications through the getMBeanInfo 55 method.

From a management point of view, the DynamicMBean behaves like any other MBean.

It is the responsibility of the implementation to ensure the MBean works as self-described. The MBeanServer makes no attempt to validate it.

Although the self-description is retrieved at runtime and is therefore dynamic, the implementation must not change it once it has been retrieved. A manager can expect the attributes, methods and notifications to remain constant. It is the implementation's responsibility to conform to this behaviour.
