| /** |
| * EntityStore backed by Preferences API. |
| * <p> |
| * A root node is created in the System preferences, whose name |
| * is the same as the Application name (default:"Application"). |
| * </p> |
| * <p> |
| * Each entity is stored under its identity name. |
| * </p> |
| * <p> |
| * Property types are converted to native Preferences API types |
| * as much as possible. All others will be serialized to a string using JSON. |
| * </p> |
| * <p> |
| * Associations are stored as the identity of the referenced Entity, ManyAssociations are stored as multi-line strings |
| * (one identity per line), and NamedAssociations are stored as multi-line strings (one name on a line, identity on the |
| * next line). |
| * </p> |
| * <p> |
| * The main use of the EntityStore is for storage of ConfigurationComposites for ServiceComposites. |
| * </p> |
