/** | |
* 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. | |
