Annotation Type PropagateNull

@Retention(RUNTIME)
@Target({PARAMETER,FIELD,METHOD,TYPE})
public @interface PropagateNull

Signals that the annotated property signals the presence of the mapped type: reflective mappers should map a null bean if this property is null, rather than a present bean with a null property value. This is useful e.g. for a LEFT OUTER JOIN or an optionally-present compound value type.
