Copyright (C) 1995-2001 Microsoft Corporation
Module Name:
MOFPARSE.CPP
Abstract:
This is a recursive descent parser for the MOF syntax.
It is based on the MOF.BNF file which defines the LL(1) MOF grammar.
In each production, nonterminals are represented by functions
with the same name.
NOTES:
(a) The lexer is implemented by class CMofLexer.
(b) Right-recursion in the grammar is consistently implemented
directly as a loop for that nonterminal.
OUTPUT:
Output is an unchecked list of classes and instances.
This is contained in the CMofData object.
Verification of output is done elsewhere, depending on the
compile context.
History:
a-raymcc 18-Oct-95 created.
a-raymcc 25-Oct-95 semantic stack operational
a-raymcc 27-Jan-96 reference & alias support
a-levn 18-Oct-96 Rewrote not to use semantic stack.
Converted to new mof syntax and new
WINMGMT interfaces.
