D.1. Optional Features
The JDO specification includes a number of optional features that a JDO implementation may or may not implement. The supportedOptions() method on PersistenceManagerFactory can be used to determine the set of optional features that a JDO implementation supports. It returns a collection of strings, one for each supported feature.
Table D-1 provides a list of these strings.
