+/**
+ * Generates a lot of code which fits with a class that is a representation of an immutable entity.
+ * Specifically, it generates:<ul>
+ * <li>Getters for all fields
+ * <li>toString method
+ * <li>hashCode and equals implementations that check all non-transient fields.
+ * <li>Generates withers for all fields (except final fields that are initialized in the field declaration itself)
+ * <li>Generates a constructor for each argument
+ * <li>Adds {@code private} and {@code final} to each field.
+ * </ul>
+ * 
+ * In other words, {@code @Value} is a shorthand for {@code @Getter @Wither @FieldDefaults(makeFinal=true,level=AccessLevel.PRIVATE) @EqualsAndHashCode @ToString @AllArgsConstructor}.
+ * <p>
+ * If any method to be generated already exists (in name - the return type or parameters are not relevant), then
+ * that method will not be generated by the Data annotation.
+ * <p>
+ * The generated constructor will have 1 parameter for each field. The generated toString will print all fields,
+ * while the generated hashCode and equals take into account all non-transient fields.<br>
+ * Static fields are skipped (no getter or setter, and they are not included in toString, equals, hashCode, or the constructor).
+ * <p>
+ * {@code toString}, {@code equals}, and {@code hashCode} use the deepX variants in the
+ * {@code java.util.Arrays} utility class. Therefore, if your class has arrays that contain themselves,
+ * these methods will just loop endlessly until the inevitable {@code StackOverflowError}. This behaviour
+ * is no different from {@code java.util.ArrayList}, though.
