41 // This header describes the cimmofParser class.
42 // It is a singleton, and can only be accessed via the pointer
43 // returned by its static Intance() method.
44 // //
45 // The instance of this
46 // class hold enough state information that there should be no need for
47 // the underlying YACC parser to be written reentrant.
48 //
49 // The YACCer (and LExer) communicate with the instance of this class
50 // via the ointer returned by the Instance() method.
51 //
52 // This specialization contains a reference to the containing program's
53 // mofComplerCmdLine object, which holds the command line arguments
54 // including the list of directories to search to find included mof files
55 //
