|
* functionality. ORB access this implementation using {@link InvokeHandler}
|
|
* ._invoke(..). All such calls are finally delegated to the object, returned by
|
|
* {@link #getTarget()}.
|

|
* Ties are generated from implementations (name pattern *Impl) and have the

|
* name pattern _*Impl_Tie, for instance:<br>
