Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

Jackson Annotations Source Code files are provided in the source packge (jackson-annotations-2.14.0-sources.jar). You can download it at Jackson Maven Website.

/**
 * Marker annotation that can be used to define a logical "any setter" mutator --
 * either using non-static
 * two-argument method (first argument name of property, second value
 * to set) or a field (of type {@link java.util.Map} or POJO) -
 * to be used as a "fallback" handler
 * for all otherwise unrecognized properties found from JSON content.
 * It is similar to {@code javax.xml.bind.annotation.XmlAnyElement}
 * in behavior; and can only be used to denote a single property
 * per type.
 *<p>
 * If used, all otherwise unmapped key-value pairs from JSON Object values
 * are added using mutator.
 *<p>
 * NOTE: ability to annotated fields was added in version 2.8; earlier only
 * methods could be annotated.
