TClingClassInfo Class Reference

Emulation of the CINT ClassInfo class.

The CINT C++ interpreter provides an interface to metadata about a class through the ClassInfo class. This class provides the same functionality, using an interface as close as possible to ClassInfo but the class metadata comes from the Clang C++ compiler, not CINT.
