IterPrev Method

Applies To

OCollection

Description

Moves iterator to point to the previous collection element.

Usage

void IterPrev(void) const throw(OException)

Arguments

none

Remarks

Accessing collection elements using iterator is faster than using index on OCollection object. If the iterator is pointing to the first element of the collection prior to executing this function, then calling this method will make the BOC property to return true. The iterator will be left unchanged in that case. BOC property should be checked when calling this method repetitively.
