39 mike 1.11 // It is a singleton, and can only be accessed via the pointer
40 // returned by its static Intance() method.
41 // //
42 // The instance of this

44 // the underlying YACC parser to be written reentrant.

46 // The YACCer (and LExer) communicate with the instance of this class
47 // via the ointer returned by the Instance() method.

49 // This specialization contains a reference to the containing program's
50 // mofComplerCmdLine object, which holds the command line arguments
51 // including the list of directories to search to find included mof files
