<h1>Description</h1>
<p>The Db.get_byteswapped method
returns false
if the underlying database files were created on an architecture of the
same byte order as the current one, and
returns true
if they were not (that is, big-endian on a little-endian machine, or
vice versa). This field may be used to determine whether application
data needs to be adjusted for this architecture or not.
<p>The Db.get_byteswapped interface may not be called before the <a href="../api_java/db_open.html">Db.open</a>
interface has been called.
<h1>Errors</h1>
<p>The Db.get_byteswapped 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 before <a href="../api_java/db_open.html">Db.open</a> was called.
</dl>
<p>The Db.get_byteswapped 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.get_byteswapped 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.
