A transient object is an object that has been activated in a POA with the ``transient'' lifespan policy. Its lifespan is bounded by the POA it was activated in, and ceases to exist if its POA instance is destroyed, for example as part of server shutdown. Note: this definition has changed in CORBA 2.3; according to CORBA 2.2, a transient object's lifespan is bounded by the lifespan of its server process.
