Examples of org.rssowl.core.persist.IEntity

org.rssowl.core.persist.IEntity
Implementors of IEntity add a certain model-type to the application. Any entity is uniquely identified by its ID. Implementors have to make sure, that no entity of any kind will ever have the same ID as another entity.
Compared to a simple IPersistable like IImage, an entity adds the following features:
- Identified by a unique ID that allows to load the entity from the persistence layer
- A Map allowing to store Properties. The content of the Map is stored into the DataBase and thereby kept persistant in case they are Serializable. This is done using Java's Serialization Feature and it is strongly recommended not to use the Properties to store complex Objects. It is very good to use with Strings or primitive Arrays. For any complex type, please consider to extend the DataBase with a new relation to store your data.
