Detailed Description

The fileEventiterator reads the event data from a data file on disk. It creates and returns pointers to Event objects. At the end of the file it returns 0 when there are no events left.

Here is the call graph for this function:

fileEventiterator::fileEventiterator	(	const char *	filename,
		int &	status
	)

This constructor gives you a status so you can learn that the creation of the fileEventiterator object was successful. If the status is not 0, something went wrong and you should delete the object again.
