Detailed Description
Represents a C++ member access expression where the actual member referenced could not be resolved because the base expression or the member name was dependent.
Like UnresolvedMemberExprs, these can be either implicit or explicit accesses. It is only possible to get one of these with an implicit access if a qualifier is provided.

| NamedDecl* clang::CXXDependentScopeMemberExpr::getFirstQualifierFoundInScope | ( | ) | const [inline] |
Retrieve the first part of the nested-name-specifier that was found in the scope of the member access expression when the member access was initially parsed.
This function only returns a useful result when member access expression uses a qualified member name, e.g., "x.Base::f". Here, the declaration returned by this function describes what was found by unqualified name lookup for the identifier "Base" within the scope of the member access expression itself. At template instantiation time, this information is combined with the results of name lookup into the type of the object expression itself (the class type of x).
| SourceLocation clang::CXXDependentScopeMemberExpr::getLAngleLoc | ( | ) | const [inline] |
