Examples of org.rssowl.core.persist.IModelFactory

org.rssowl.core.persist.IModelFactory
Provides access to the model factory of RSSOwl. This factory is used everywhere when new entities are created. The factory can be replaced using the ModelFactory extension point. @author Ismael Juma (ismael@juma.uk)
