public interface RMIConnection extends Remote
RMI object used to forward an MBeanServer request from a client to its MBeanServer implementation on the server side. There is one Remote object implementing this interface for each remote client connected to an RMI connector.
User code does not usually refer to this interface. It is specified as part of the public API so that different implementations of that API will interoperate.
To ensure that client parameters will be deserialized at the
server side with the correct classloader, client parameters such as
parameters used to invoke a method are wrapped in a {@link
MarshalledObject}. An implementation of this interface must first
get the appropriate class loader for the operation and its target,
then deserialize the marshalled parameters with this classloader.
Except as noted, a parameter that is a
MarshalledObject or MarshalledObject[]
must not be null; the behavior is unspecified if it is.
Class loading aspects are detailed in the JMX Specification, version 1.4 PDF document.
Most methods in this interface parallel methods in the {@link
MBeanServerConnection} interface. Where an aspect of the behavior
of a method is not specified here, it is the same as in the
corresponding MBeanServerConnection method.

Register for notifications from the given MBeans that match the given filters. The remote client can subsequently retrieve the notifications using the {@link #fetchNotifications fetchNotifications} method.
For each listener, the original
NotificationListener and handback are
kept on the client side; in order for the client to be able to
identify them, the server generates and returns a unique
listenerID. This listenerID is
forwarded with the Notifications to the remote
client.
If any one of the given (name, filter) pairs cannot be registered, then the operation fails with an exception, and no names or filters are registered.

Retrieves notifications from the connector server. This method can block until there is at least one notification or until the specified timeout is reached. The method can also return at any time with zero notifications.
A notification can be included in the result if its sequence
number is no less than clientSequenceNumber and
this client has registered at least one listener for the MBean
generating the notification, with a filter that accepts the
notification. Each listener that is interested in the
notification is identified by an Integer ID that was returned
by {@link #addNotificationListeners(ObjectName[],
MarshalledObject[], Subject[])}.

client is interested in. If negative, it is interpreted as
meaning the sequence number that the next notification will

more elements than this if the same notification appears more
than once. The behavior is unspecified if this parameter is
negative.timeout - the maximum time in milliseconds to wait for a
notification to arrive. This can be 0 to indicate that the
method should not wait if there are no notifications, but
should return at once. It can be Long.MAX_VALUE
