19// Emulation of the CINT TypeInfo class. //
20// //
21// The CINT C++ interpreter provides an interface to metadata about //
22// a type through the TypeInfo class. This class provides the same //
23// functionality, using an interface as close as possible to TypeInfo //
24// but the type metadata comes from the Clang C++ compiler, not CINT. //
