- RMIConnectionImpl, RMIConnectionImpl_Stub
public interface RMIConnection extends Closeable, 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
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 aMarshalledObject
orMarshalledObject[]
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
MBeanServerConnection
interface. Where an aspect of the behavior of a method is not specified here, it is the same as in the correspondingMBeanServerConnection
method.- Since:

getConnectionId
String getConnectionId() throws IOException
Returns the connection ID. This string is different for every open connection to a given RMI connector server.
- Returns:
- the connection ID
- Throws:
IOException
- if a general communication exception occurred.- See Also:
RMIConnector.connect
-
close
void close() throws IOException
Closes this connection. On return from this method, the RMI object implementing this interface is unexported, so further remote calls to it will fail.
- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Throws:
IOException
- if the connection could not be closed, or the Remote object could not be unexported, or there was a communication failure when transmitting the remote close request.
