        public static <T> HostForwarding getInstance​(java.lang.Class<T> asInterface,
                                             javax.management.MBeanServer mBeanServer,
                                             java.lang.String query)
        Get a host forwarding instance. As a side effect of this, all mbeans matching a query from remote hosts, are proxied and registered in the given mbean server. Only one HostForwarding instance will be made for each query string. Any subsequent call with the same query string will simply return the previously initiated instance.
        Type Parameters:
        T - The type of HostForwarding to return.
        Parameters:
        asInterface - The interface remote mbeans should implement.
        mBeanServer - The MBean server to register proxy mbeans in.
        query - The query for which we should proxy matching mbeans on remote servers.
        Returns:
        This host forwarding instance.
