29 Module salome gives access to Salome resources.
34 - salome.naming_service : instance of naming Service class
36 - Resolve(name) : find a CORBA object (ior) by its pathname
37 - Register(name) : register a CORBA object under a pathname
39 - salome.lcc : instance of lifeCycleCORBA class
41 - FindOrLoadComponent(server,name) :
42 obtain an Engine (CORBA object)
43 or launch the Engine if not found,
44 with a Server name and an Engine name
46 - salome.sg : salome object to communicate with the graphical user interface (if any)
50 - SelectedCount(): returns number of selected objects
51 - getSelected(i): returns entry of selected object number i
52 - getAllSelected(): returns list of entry of selected objects
53 - AddIObject(Entry): select an existing Interactive object
54 - RemoveIObject(Entry): remove object from selection
55 - ClearIObjects(): clear selection
63 - IDToObject(Entry): returns CORBA reference from entry
65 - salome.myStudyName : active Study Name
66 - salome.myStudy : the active Study itself (CORBA ior)
67 - methods : defined in SALOMEDS.idl
71 # Module salome gives access to Salome resources.
73 # \param salome.orb : CORBA orb object
74 # \param salome.naming_service : instance of naming Service class (SALOME_NamingServicePy::SALOME_NamingServicePy_i)
75 # \param salome.lcc : instance of lifeCycleCORBA class (SALOME_LifeCycleCORBA)
76 # \param salome.sg : Salome object to communicate with the graphical user interface, if running (see interface in salome_iapp::SalomeOutsideGUI)
