Type Traits of vc8 is used to obtain the type information during compilation. In the boost library, many strange methods are used to detect the type information. It is mainly a template-specific mechanism. For example, whether two types have been:

QString Str ("Hello");QString str = "Hello";static const Qchar Data[4] = {0x0055, 0x006e, 0x10e3, 0x03a3};QString Str (data, 4);QString str;Str.resize (4);Str[0] = Qchar (' U ');STR[1] = Qchar (' n ');STR[2] = Qchar (0X10E3);STR[3] = Qchar
