    <p><a href="http://download.oracle.com/javase/7/docs/api/java/io/DataInput.html#readBoolean%28%29"><code>readBoolean()</code></a> reads a single byte. <a href="http://download.oracle.com/javase/7/docs/api/java/io/DataInput.html#readLine%28%29"><code>readLine()</code></a> reads single bytes and converts each to a <code>char</code>.</p> <p><a href="http://download.oracle.com/javase/7/docs/api/java/io/DataInput.html#readUTF%28%29"><code>readUTF()</code></a> reads modified UTF-8 (which has a code unit size of one octet). UTF-8 has <a href="http://unicode.org/faq/utf_bom.html#utf8-2">no endianness</a>.</p> <p>There are no endianness concerns with these methods.</p> <p>As to the design, consider whether the type needs to be an <code>InputStream</code> and whether the <a href="http://download.oracle.com/javase/7/docs/api/java/nio/ByteBuffer.html"><code>ByteBuffer</code></a> might be useful. If you weren't using features like mark/reset and <a href="http://download.oracle.com/javase/7/docs/api/java/io/Closeable.html"><code>Closeable</code></a> you might not expose the new type:</p> <pre><code>public class Bytes { public static DataInput littleEndian(final DataInput decorated) { class LittleInput implements DataInput { private ByteBuffer buffer = ByteBuffer.allocate(8); public int readInt() throws IOException { buffer.clear(); buffer.order(ByteOrder.BIG_ENDIAN) .putInt(decorated.readInt()) .flip(); return buffer.order(ByteOrder.LITTLE_ENDIAN) .getInt(); } //TODO: other methods } return new LittleInput(); } } </code></pre> <p>I note that the popular Guava library already has <a href="http://docs.guava-libraries.googlecode.com/git-history/v10.0.1/javadoc/com/google/common/io/LittleEndianDataInputStream.html">LittleEndianDataInputStream</a>.</p>

    1. COThank you. Is Guava available as part of the standard Java runtime platform that most people already have on their computers?

    3. COThe ESRI shapefile format mixes both little and big endian in a single format, so I wanted to provide both types from a single class as I did here.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
