Re: [cdt-dev] Getting methods/fields from CPPClassTemplate

[Neeraj U Bhope <neerajbhope@xxxxxxxxxx>]

I have attached a trivial patch which
adds the implementations for the get* methods in CPPClassTemplate. As you
have indicated the implementation is same as that in CPPClassType and hence
there is code replication here..however, I am not sure if we need to refactor
and if yes then what would be a good place to refactor the code into. It
would be great if somebody can review the patch. Andrew?
