Detailed Description

template<class Object>
class eoAged< Object >

eoAge is a template class that adds an age to an object.

\ Requisites for template instantiation are that the object must admit a default ctor and a copy ctor. The Object must be an eoObject, thus, it must have its methods: className, printOn, readFrom.

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

void

)

This should be redefined in each class; but it's got code as an example of implementation. Only "leaf" classes can be non-virtual.

virtual void eoAged< Object >::readFrom

(

istream &

_is

)

A istream.

runtime_exception

If a valid object can't be read.

virtual void eoAged< Object >::printOn

(

ostream &
