public abstract class POAHelper
extends java.lang.Object
```
A POA object manages the implementation of a collection of objects. The POA supports a name space for the objects, which are identified by Object Ids. A POA also provides a name space for POAs. A POA is created as a child of an existing POA, which forms a hierarchy starting with the root POA. A POA object must not be exported to other processes, or externalized with ORB::object_to_string.
