The PoolScan class provides a convenient interface for scanning through the objects in a pool in Shore VAS clients. This document describes how to use PoolScans, as well as known bugs and limitations of the PoolScan class. The Shore release includes three example programs that illustrate pool scans. The examples can be found in the examples/pscan directory of the Shore release. The PoolScan class is part of the SDL library, but it is not necessary to use SDL or the SDL compiler to use it.
