+/**
+ * The {@code @Jacksonized} annotation is an add-on annotation for
+ * {@code @}{@link Builder} and {@code @}{@link SuperBuilder}. It automatically
+ * configures the generated builder class to be used by Jackson's
+ * deserialization. It only has an effect if present at a context where there is
+ * also a {@code @Builder} or a {@code @SuperBuilder}; a warning is emitted
+ * otherwise.
+ * <p>
+ * In particular, the annotation does the following:
+ * <ul>
+ * <li>Configure Jackson to use the builder for deserialization using
+ * {@code @JsonDeserialize(builder=MyClass.MyClassBuilder[Impl].class))} on the
+ * class. (An error is emitted if such an annotation already exists.)
+ * <li>Copy Jackson-related configuration annotations (like
+ * {@code @JsonIgnoreProperties}) from the class to the builder class. This is
+ * necessary so that Jackson recognizes them when using the builder.
+ * <li>Insert {@code @JsonPOJOBuilder(withPrefix="")} on the generated builder
+ * class to override Jackson's default prefix "with". If you configured a
+ * different prefix in lombok using {@code setterPrefix}, this value is used. If
+ * you changed the name of the {@code build()} method using using
+ * {@code buildMethodName}, this is also made known to Jackson.
+ * <li>For {@code @SuperBuilder}, make the builder implementation class
+ * package-private.</li>
+ * </ul>
+ * This annotation does <i>not</i> change the behavior of the generated builder.
+ * A {@code @Jacksonized} {@code @SuperBuilder} remains fully compatible to
+ * regular {@code @SuperBuilder}s.
