Can anyone, pleeese, tell me why this extractor operator is not causing this 
error:
C:\tmp\adfs\main.cpp|20|error: no match for 'operator<<' (operand types are 
'std::wostream {aka std::basic_ostream<wchar_t>}' and 
'std::unique_ptr<jme::Name>')|

namespace abc{
class MyClass{
   private:
   int nuestro;
   public:
   MyClass(){}
   virtual MyClass(){}
   friend std::wostream& operator<<( std::wostream& os, const abc::Name& 
obj );
};//class

}//namespace abc

cpp file
~~~~~~~~
namespace abc{
std::wostream& operator<<(abc::wostream& os, const abc::Name& obj) {
   return os << obj.getFirstName() << " "
         << obj.getMiddleName() << " "
           << obj.getLastName();
   }//operator<<
} // namespace
