| /** |
| * The NonCacheable annotation is used to configure caching behavior for |
| * relationships. If this annotation is set on a relationship that relationship |
| * will not be cached even though the parent Entity may be cached. Each time the |
| * Entity is retrieved the relationship will be reloaded from the data-source. |
| * |
| * This may be useful for situations where caching of relationships is not |
| * desired or when using different EclipseLink IdentityMap types and having |
| * cached references extends the cache lifetime of related Entities using a |
| * different caching scheme. |
| * For instance Entity A references Entity B, Entity A is FullIdentityMap and |
| * Entity B is WeakIdentityMap. Without removing the caching of the relationship |
| * the Entity B's cache effectively become a FullIdentityMap. |
