Abstract
An open address probing barrier is utilized in association with a memory container. A starting memory slot is calculated for an item to be found in the memory container. Responsive to the item failing to occupy the starting memory slot, a first predetermined number of memory slots immediately following the starting memory slot are probed. Responsive to the item occupying one of those memory slots, the item is returned to the application. Responsive to the item failing to occupy one of those memory slots, a determination is made as to whether a barrier bit has been set in association with the last of the first predetermined number of memory slots. If so, at least a portion of the memory container is probed for the item and, if found, the item is returned to the application. If the barrier bit is not set, a notification is returned to the application.
