| /** |
| * <p> |
| * <b>Purpose</b>: This class provides an implementation of an internal RCM Command. |
| * </p> |
| * <p> |
| * <b>Description</b>: This command is used by the RCM when it receives a connection |
| * from a remote service. It adds the connection to its own list, and then sends this command |
| * back to the remote service to establish the backward connection from the remote service to |
| * this service, accompanying the command with a reference to this own service id. The |
| * remote service can then create a connection using the service id stored in the command and |
| * add the connection to its connection list. |
| * </p> |
