Examples of org.jpox.PersistenceConfiguration

org.jpox.PersistenceConfiguration
Class providing configuration for persistence. Persistence properties should be defined in the "plugin.xml" of the plugin that originates them. This class will read the available defined plugin properties (and their defaults, validators etc) and loaded up accordingly. Then any user-provided properties are superimposed over the top of these. Components can then access these properties using any of the convenience accessors for boolean, Boolean, long, int, Object, String types.
