[cfe-dev] How to get the template argument type from AST matcher?

[Manuel Klimek]

It actually depends on what you want :) Do you want
a) the name of the class (then what Nicola wrote is good)
b) what the user wrote as template argument; in that case, you'd want to
get the TypeLoc at that point, and then use Lexer::getSourceText
