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