023 * An extension of {@code DataInput} for reading from in-memory byte arrays; its
024 * methods offer identical functionality but do not throw {@link IOException}.
025 *
026 * <p><b>Warning:<b> The caller is responsible for not attempting to read past
027 * the end of the array. If any method encounters the end of the array
028 * prematurely, it throws {@link IllegalStateException} to signify <i>programmer
029 * error</i>. This behavior is a technical violation of the supertype's
030 * contract, which specifies a checked exception.
