Detailed Description

AP_NormalisedEventIterator.

External (client-visible) interface to a normalised event iterator object. The AP_NormalisedEventIterator struct contains a table of function pointers, declared in the AP_NormalisedEventIterator_Functions struct above. The implementation of these functions is private. Users of the iterator should invoke functions on it as in the following example (iterator is of type AP_NormalisedEventIterator*):

b = iterator->functions->valid(iterator);

Note that an iterator is only valid as long as the underlying normalised event remains unchanged. Any iterators on a given event should be deleted as soon as any operation is performed that might change the contents of the event object.
