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