Interface MBeanServerInterceptor

All Known Implementing Classes:
  DefaultMBeanServerInterceptor

public interface MBeanServerInterceptor

MBeanServer --> MBean interceptor. These interceptors are used internally to implement MBeanServer functionality prior to call MBeans, and can be used to customize MBeanServer implementation by users.
