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 indicates that all properties that have
 * type annotated with this annotation
 * are to be ignored during serialization and deserialization.
 *<p>
 * Note that this does NOT mean that properties included by annotated
 * type are ignored. Given hypothetical types:
 *<pre>
 *  {@code @JsonIgnoreType}
 *  class Credentials {
 *     public String password;
 *  }
 *
 *  class Settings {
 *     public int userId;
 *     public String name;
 *     public Credentials pwd;
 *  }
 *</pre>
 * serialization of {@code Settings} would only include properties "userId"
 * and "name" but NOT "pwd", since it is of type annotated with {@code @JsonIgnoreType}.
 *<p>
 * Note: annotation does have boolean 'value' property (which defaults
 * to 'true'), so that it is actually possible to override value
 * using mix-in annotations. Usually value is not specified as it defaults
 * to {@code true} meaning annotation should take effect.
