Annotation Interface Join

@Retention(RUNTIME) @Target({METHOD,FIELD}) public @interface Join
Indicates that the property value is set by joining from another table (pojo class). You may use this on a single object (one to one, many to one), or on a collection (one to many, many to many). If joining to a collection, make sure that you instantiate it as a modifiable collection. Persism will not do that fo you.
