/**
 * Annotation used to indicate that annotated property is part of
 * two-way linkage between fields; and that its role is "parent" (or "forward") link.
 * Value type (class) of property must have a single compatible property annotated with
 * {@link JsonBackReference}. Linkage is handled such that the property
 * annotated with this annotation is handled normally (serialized normally, no
 * special handling for deserialization); it is the matching back reference
 * that requires special handling
 *

* All references have logical name to allow handling multiple linkages; typical case * would be that where nodes have both parent/child and sibling linkages. If so, * pairs of references should be named differently. * It is an error for a class too have multiple managed references with same name, * even if types pointed are different. *

* Note: only methods and fields can be annotated with this annotation: constructor * arguments should NOT be annotated, as they can not be either managed or back * references. * * @author tatu */ @Target({ElementType.ANNOTATION_TYPE, ElementType.FIELD, ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) @JacksonAnnotation public @interface JsonManagedReference { /** * Logical have for the reference property pair; used to link managed and * back references.
