58 \class SALOME::GenericObj_i
59 \brief Implementation of the base servant for SALOME objects with reference counter.
61 This class can be used to implement data entities with life-cycle management based on
62 the reference counting.
64 The object is initially created with the reference counter equal to 1.
65 The function Register() can be used to incrfement the reference counter.
66 Function UnRegister() should be used to decrement reference counter.
67 As soon as reference counter goes to zero, the object is automatically deactivated in POA
68 (and, eventually its destructor is automatically called).
73 Creates an object with the reference counter initially set to 1.
75 The default POA for the servant can be passed as a parameter \a thePOA.
76 By default, root POA is used.
78 \param thePOA optional default POA for the servant
