public void set_lorder(int lorder)
    throws DbException;
</pre></h3>
<h1>Description</h1>
<p>Set the byte order for integers in the stored database metadata.  The
number should represent the order as an integer; for example, big endian
order is the value 4,321, and little endian order is the value 1,234.
If <b>lorder</b> is not explicitly set, the host order of the machine
where the Berkeley DB library was compiled is used.
<p><b>The access methods provide no guarantees about the byte ordering of the
application data stored in the database, and applications are responsible
for maintaining any necessary ordering.</b>
<p>The Db.set_lorder method configures a database, not only operations performed
using the specified <a href="../api_java/db_class.html">Db</a> handle.
<p>The Db.set_lorder interface may not be called after the <a href="../api_java/db_open.html">Db.open</a>
interface is called.
If the database already exists when
<a href="../api_java/db_open.html">Db.open</a> is called, the information specified to Db.set_lorder will
be ignored.
If creating additional databases in a file, the byte order specified must
be consistent with the existing databases in the file or an error will be
returned.
<p>The Db.set_lorder method throws an exception that encapsulates a non-zero error value on
failure.
<h1>Errors</h1>
<p>The Db.set_lorder method may fail and throw an exception encapsulating a non-zero error for the following conditions:
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
<p>Called after <a href="../api_java/db_open.html">Db.open</a> was called.
</dl>
<p>The Db.set_lorder method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the Db.set_lorder method may fail and
throw a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>,
in which case all subsequent Berkeley DB calls will fail in the same way.
