|
|
* extending RelationSupport, to retrieve the implementations of required
|
|
* interfaces (see below).
|
|
* <P>It is also possible to have in a user relation MBean class a member
|
|
* being a RelationSupport object, and to implement the required interfaces by
|
|
* delegating all to this member.
