100b57cec5SDimitry Andric /// This file implements an ASTConsumer for consuming model files.

120b57cec5SDimitry Andric /// This ASTConsumer handles the AST of a parsed model file. All top level
130b57cec5SDimitry Andric /// function definitions will be collected from that model file for later
140b57cec5SDimitry Andric /// retrieval during the static analysis. The body of these functions will not
150b57cec5SDimitry Andric /// be injected into the ASTUnit of the analyzed translation unit. It will be
160b57cec5SDimitry Andric /// available through the BodyFarm which is utilized by the AnalysisDeclContext
170b57cec5SDimitry Andric /// class.
