Constructor & Destructor Documentation

template<class Object> eoAged< Object >::eoAged (   )  [inline, private]

Default Constructor. \ It´s private so that it is not used anywhere; the right way of using this object is to create an Object and passing it to an aged by means of the copy ctor; that way it´s turned into an Aged object Definition at line 103 of file eoAged.h.

Member Function Documentation

template<class Object> virtual std::string eoAged< Object >::className (   )  const [inline, virtual]

template<class Object> virtual void eoAged< Object >::readFrom (  istream &  _is  )  [inline, virtual]

Read object. Parameters: _is  A istream. Exceptions: runtime_exception  If a valid object can't be read. Definition at line 81 of file eoAged.h.

template<class Object> virtual void eoAged< Object >::printOn (  ostream &  _os  )  const [inline, virtual]
