Sources Available at the Enumeration, Generation, and Shutdown Stages

At the Enumeration and Generation stages, the same data sources are available as in the Data stage. See Table 12–3 for information.

At the Shutdown stage, the filter completes its filtering and shuts down. Although functions written for this stage can use the same data sources as those available at the Data stage, the shutdown functions typically restrict their operations to robot shutdown and clean-up activities.
