class CXXTypeidExpr

Declaration

class CXXTypeidExpr : public Expr { /* full declaration omitted */ };

Description

A C++ \c typeid expression (C++ [expr.typeid]), which gets the \c type_info that corresponds to the supplied type, or the (possibly dynamic) type of the supplied expression. This represents code like \c typeid(int) or \c typeid(*objPtr)
