After a discussion with Ted, we both came to the conclusion that adding a "HandleTopLevelDeclaration" hook to ASConsumer is far more elegant. The default implementation of HandleTopLevelDeclaration will be responsible for iterating over the ScopedDecl (which has a chain of the decls:-).

Ted Kremenek [Thu, 29 Nov 2007 23:05:17 +0000 (23:05 +0000)]
Added method "HandleTopLevelDeclaration" to ASTConsumer. This will eventually
be the new hook that ASTStreamer calls to feed top-level Decls to
ASTConsumers.

The difference between "HandleTopLevelDeclaration" and "HandleTopLevelDecl" is
that "HandleTopLevelDecl" is currently called by ASTStreamer for every
top-level declaration, including those that appear within a Decl chain. Using
the new interface, ASTStreamer would only call HandleTopLevelDeclaration for
Decls that appear that the beginning of a Decl chain (i.e., a group of related
decls).

To preserve the behavior that all subclasses of ASTConsumer currently expect,
the default implementation of HandleTopLevelDeclaration simply calls
HandleTopLevelDecl, and for decl chains it calls HandleTopLevelDecl for each
Decl* in a chain of Decls.

The advantage of this interface is that some subclasses of ASTConsumer only
really want the Decl chain, and not each individual Decl passed to them. This
extra level of indirection allows subclasses to override the default behavior
if they so desire.
