|
<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>
