Eventiterators access your raw data

An Eventiterator gives you one Event object at a time, until it is empty (or you decide to stop).

int main ()

{

Eventiterator * it =

new testEventiterator();

Event *evt;

while ( evt = it->getNextEvent() )

{

evt->identify();

delete evt;

}

delete it;

return 0;

}

int main ()

{

Eventiterator * it =

new fileEventiterator ("xx.evt");

Event *evt;

while ( evt = it->getNextEvent() )

{

evt->identify();

delete evt;

}

delete it;

return 0;

}

file

int main ()

{

Eventiterator * it =

new ddEventiterator ("online");

Event *evt;

while ( evt = it->getNextEvent() )

{

evt->identify();

delete evt;

}

delete it;

return 0;

}
