+
+ <p>Invoking the BoostCon tool:</p>
+ <pre>
+$ clang -cc1 -boostcon t.cpp
+</pre>
+
+ <p>Teach the BoostCon action to identify and print C++ classes:</p>
+ <pre>
+bool VisitCXXRecordDecl(CXXRecordDecl *D) {
+ std::cout << D->getNameAsString()
+ << '\n';
+ return false;
+}
+</pre>
+
+ <p>Walk and print base classes of a class:</p>
+ <pre>
+for(CXXRecordDecl::base_class_iterator
+ B = D->bases_begin(), BEnd = D->bases_end();
+ B != BEnd; ++B) {
+ QualType BaseType = B->getType();
+ std::cout << " " << BaseType.getAsString()
+ << '\n';
+}
+</pre>
+
+ <p>Retrieve the C++ class declaration from a base type:</p>
+ <pre>
+if (const RecordType *RTy
+ = BaseType->getAs<RecordType>()) {
+ RecordDecl *Base = RTy->getDecl();
+ if (CXXRecordDecl *BaseCXX
+ = dyn_cast<CXXRecordDecl>(Base)) {
+
+ }
+}
+</pre>
