public class ObjectId

extends java.lang.Object

implements Immutable, java.lang.Cloneable, java.io.Serializable

An object identifier addresses a remote object and all its proxy objects. The object identifier is a list of addresses shown in the following diagram:

              next              next
    ObjectId -------> ObjectId -....-> null
       |                 | 
       | utid            | utid
       |                 | 
       v                 v
      UTID              UTID
       |                 | 
       | next            | next
       |                 | 
       v                 v
      UTID              UTID
       .                 .
       . next            . next
       v                 v
      null              null
 

The first column represents the address space of the server implementation. The other columns are addresses of proxy objects.

An export point in a remote address space can be reached over one or more technologies. All suitable technologies are linked together in a row.

If the server implementation is local, the first UTID in the first column directly references a local export point via its UTID.ep member.

To communicate with the referenced remote object it is necessary to support at least one referenced technology. To access the remote object, the matching UTID and the ObjectId at the top of the corresponding column is used.

There are no two UTID objects that belong to the same technology domain.

Objects of this class are sent over the network by KaRMI.
