With

Returns the real class name of any class inheriting from Object. The name returned is dependant on the ISO C++ compiler's implementation, but two different classes should always, with the same compiler, have different names.

Note:

the class name given by the compiler depends on the compiler and its version.

g++ 3.x, the classname is prefixed with the character length: Lockable classname would be actually 8Lockable, Log would be 3Log.
