+ * Generates getters for all fields, a useful toString method, and hashCode and equals implementations that check
+ * all non-transient fields. Will also generate setters for all non-final fields, as well as a constructor.
+ * <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 final 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.
