33 // This header describes the cimmofParser class.
34 // It is a singleton, and can only be accessed via the pointer
35 // returned by its static Intance() method.
36 // //
37 // The instance of this
38 // class hold enough state information that there should be no need for
39 // the underlying YACC parser to be written reentrant.
40 mike 1.11 //
41 // The YACCer (and LExer) communicate with the instance of this class
42 // via the ointer returned by the Instance() method.
43 //
44 // This specialization contains a reference to the containing program's
45 // mofComplerCmdLine object, which holds the command line arguments
46 // including the list of directories to search to find included mof files
