Thread: Objects or pointers in STL containers?

G'day,

Doing a little input manager for a project of mine. Basically I have an input event (InputEvent), which is a simple, small class. And then a user-defined function which takes an std::queue<InputEvent>.

The user-defined function is called about 100 times a second. With say a max of 10 input events per-call. Is it wise to be storing InputEvent objects in the queue or should I be storing pointers?

Basically I don't want to make the user free the InputEvent pointers themselves.

Secondly, should I specifically make my InputEvent copyable (ie override operator=)?

In short I have,

My library

Code:

// ...

std::queue<InputEvent> events_;

// ... add the events to the queue

events_.push(InputEvent(x, y));
events_.push(InputEvent(x, y));
events_.push(InputEvent(x, y));

client->frame(&events_);

// ...

User's code

Code:

void frame(std::queue<InputEvent> * events)
{
    // the InputEvents are removed from the queue
}

Thanks!
Zac
