  namespace Poco {
  
  class Foundation_API Void
A dummy class with value-type semantics, mostly useful as a template argument. This class is typically used together with ActiveMethod, if no argument or return value is needed. { public: Void(); Creates the Void. 

          Void(const Void& v);
Creates the Void from another Void. The philosophical aspects of this operation remain undiscussed for now. ~Void(); Destroys the Void. 

          Void& operator = (const Void& v);
Assigns another void. 

          bool operator ==(const Void& v) const;
Will return always true due to Voids having no members. 

          bool operator !=(const Void& v) const;
Will return always false due to Voids having no members. }; 

  inline bool Void::operator ==(const Void& v) const
  {
          return true;
  }
  
  inline bool Void::operator !=(const Void& v) const
  {
          return false;
