JmxMBeanServer.java 文件源码

/**
 * <b>Package:</b> Creates an MBeanServer.
 * @param domain The default domain name used by this MBeanServer.
 * @param outer A pointer to the MBeanServer object that must be
 *        passed to the MBeans when invoking their
 *        {@link javax.management.MBeanRegistration} interface.
 * @param delegate A pointer to the MBeanServerDelegate associated
 *        with the new MBeanServer. The new MBeanServer must register
 *        this MBean in its MBean repository.
 * @param instantiator The MBeanInstantiator that will be used to
 *        instantiate MBeans and take care of class loading issues.
 * @param metadata The MetaData object that will be used by the
 *        MBean server in order to invoke the MBean interface of
 *        the registered MBeans.
 * @param interceptors If <code>true</code>,
 *        {@link MBeanServerInterceptor} will be enabled (default is
 *        <code>false</code>).
 * @param fairLock If {@code true}, the MBean repository will use a {@link
 *        java.util.concurrent.locks.ReentrantReadWriteLock#ReentrantReadWriteLock(boolean)
 *        fair locking} policy.
