| /** The EntityToValueService converts Entities to matching Values. |
| * <p> |
| * The main purpose of this service is to provide convenience to map entities to serializable values, for instance |
| * to be transported across a network. The ValueComposite to convert the Entity to must closely match the Entity |
| * for this mapping to work. The rules are fairly straight forward; |
| * </p> |
| * <ol> |
| * <li>Any Property in the EntityComposite to be mapped, must (by default) exist in the ValueComposite with the same |
| * fully qualified name, i.e. method declared in the same interface. If the ValueComposite is annotated with |
| * @Unqualified then the Property method look up will only locate the properties with the name only, |
| * i.e. the methods may defined in different interfaces.</li> |
| * <li>For any Association in the EntityComposite, a Property<String> with the same <strong>unqualified</strong> |
| * name will be looked up in the ValueComposite. If found, the EntityReference of the Association will be |
| * converted to an URI and written to the String property.</li> |
| * <li>For any ManyAssociation in the EntityComposite, a Property<List<String>> with the same <strong> |
| * unqualified</strong> name will be looked up in the ValueComposite. If found, the EntityReferences in the |
| * ManyAssociation will be converted to URIs and placed into a List and set to the Property in ValueComposite.</li> |
| * <li>For any NamedAssociation in the EntityComposite, a Property<Map<String,String>> with the same |
| * <strong>unqualified</strong> name will be looked up in the ValueComposite. If found, the EntityReferences in |
| * the NamedAssociation will be converted to URIs and placed into a Map and set to the Property in ValueComposite. |
| * </li> |
| * |
| * </ol> |
| * <p> |
| * If a Property from the Entity is not found in the Value, then it is ignored. |
| * </p> |
| * @deprecated Please use {@link org.qi4j.api.unitofwork.UnitOfWork#toValue(Class, Identity)} instead. |
