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

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

/**
 * We also want to directly support deserialization of {@link TokenBuffer}.

 * Note that we use scalar deserializer base just because we claim
 * to be of scalar for type information inclusion purposes; actual
 * underlying content can be of any (Object, Array, scalar) type.
 *<p>
 * Since 2.3, another important thing is that possible native ids
 * (type id, object id) should be properly copied even when converting
 * with {@link TokenBuffer}. Such ids are supported if (and only if!)
 * source {@link JsonParser} supports them.
