  13. 	 * When the POA has the NON_RETAIN policy it uses servant 

  14. 	 * managers that are ServantLocators. Because the POA 

  15. 	 * knows that the servant returned by this servant 

  16. 	 * manager will be used only for a single request, 

  17. 	 * it can supply extra information to the servant 

  18. 	 * manager's operations and the servant manager's pair 

  19. 	 * of operations may be able to cooperate to do 

  20. 	 * something different than a ServantActivator. 

  21. 	 * When the POA uses the ServantLocator interface, 

  22. 	 * immediately after performing the operation invocation 

  23. 	 * on the servant returned by preinvoke, the POA will 

  24. 	 * invoke postinvoke on the servant manager, passing the 

  25. 	 * ObjectId value and the Servant value as parameters 

  26. 	 * (among others). This feature may be used to force 

  27. 	 * every request for objects associated with a POA to 

  28. 	 * be mediated by the servant manager.
