Annotation Type JacksonInject

@Target(value={ANNOTATION_TYPE,METHOD,FIELD,PARAMETER})
 @Retention(value=RUNTIME)
public @interface JacksonInject

Jackson-specific annotation used for indicating that value of annotated property will be "injected", i.e. set based on value configured by ObjectMapper (usually on per-call basis). Usually property is not deserialized from JSON, although it possible to have injected value as default and still allow optional override from JSON.
