45 // This header describes the cimmofParser class.
46 // It is a singleton, and can only be accessed via the pointer
47 // returned by its static Intance() method.
48 // //
49 // The instance of this
50 // class hold enough state information that there should be no need for
51 // the underlying YACC parser to be written reentrant.
52 //
53 // The YACCer (and LExer) communicate with the instance of this class
54 // via the ointer returned by the Instance() method.
55 //
56 // This specialization contains a reference to the containing program's
57 // mofComplerCmdLine object, which holds the command line arguments
58 // including the list of directories to search to find included mof files
59 //
