Name

POA

Synopsis

A POA is associated with each CORBA server object running within a given ORB. Each POA can manage one or more CORBA servants. POAs are hierarchical and define a hierarchical namespace for the servants that they manage. The root POA is supplied by the ORB itself; it can be accessed using ORB.resolve_initial_references("RootPOA"). Child POAs can be created using the create_POA() method, specifying the name for the POA relative to its parent, the POAManager to be used for the POA, and any Policy objects to be applied to the POA.
