12*0b57cec5SDimitry Andric /// This ASTConsumer handles the AST of a parsed model file. All top level
13*0b57cec5SDimitry Andric /// function definitions will be collected from that model file for later
14*0b57cec5SDimitry Andric /// retrieval during the static analysis. The body of these functions will not
15*0b57cec5SDimitry Andric /// be injected into the ASTUnit of the analyzed translation unit. It will be
16*0b57cec5SDimitry Andric /// available through the BodyFarm which is utilized by the AnalysisDeclContext
17*0b57cec5SDimitry Andric /// class.
