<div class="block">The root of all BDB JE-defined exceptions.
|
|
|
|
<p>Exceptions thrown by BDB JE fall into three categories.</p>
|
|
<ol>
|
|
<li>When a method is used incorrectly as the result of an application
|
|
programming error, a standard Java runtime exception is thrown: <code>IllegalArgumentException</code>, <code>IllegalStateException</code> or <code>UnsupportedOperationException</code>. These exceptions have the standard meaning
|
|
defined by their javadoc. Note that JE throws <code>IllegalArgumentException</code> rather than <code>NullPointerException</code> when a
|
|
required parameter is null.
|
|
</li>
|
|
<li>When an operation failure occurs, <a href="../../../com/sleepycat/je/OperationFailureException.html" title="class in com.sleepycat.je"><code>OperationFailureException</code></a> or
|
|
one of its subclasses is thrown. See <a href="../../../com/sleepycat/je/OperationFailureException.html" title="class in com.sleepycat.je"><code>OperationFailureException</code></a> for
|
|
details.
|
|
</li>
|
|
<li>When an <code>Environment</code> failure occurs, <a href="../../../com/sleepycat/je/EnvironmentFailureException.html" title="class in com.sleepycat.je"><code>EnvironmentFailureException</code></a> or one of its subclasses is thrown. See <a href="../../../com/sleepycat/je/EnvironmentFailureException.html" title="class in com.sleepycat.je"><code>EnvironmentFailureException</code></a> for details.
|
|
</li>
|
|
</ol>
|
|
|
|
<p><a href="../../../com/sleepycat/je/OperationFailureException.html" title="class in com.sleepycat.je"><code>OperationFailureException</code></a> and <a href="../../../com/sleepycat/je/EnvironmentFailureException.html" title="class in com.sleepycat.je"><code>EnvironmentFailureException</code></a>
|
|
are the only two direct subclasses of <code>DatabaseException</code>.</p>
|
|
|
|
<p>(Actually the above statement is not strictly correct. <a href="../../../com/sleepycat/je/EnvironmentFailureException.html" title="class in com.sleepycat.je"><code>EnvironmentFailureException</code></a> extends <a href="../../../com/sleepycat/je/RunRecoveryException.html" title="class in com.sleepycat.je"><code>RunRecoveryException</code></a> which
|
|
extends <code>DatabaseException</code>. <a href="../../../com/sleepycat/je/RunRecoveryException.html" title="class in com.sleepycat.je"><code>RunRecoveryException</code></a> exists for
|
|
backward compatibility and has been deprecated. <a href="../../../com/sleepycat/je/EnvironmentFailureException.html" title="class in com.sleepycat.je"><code>EnvironmentFailureException</code></a> should be used instead.)</p>
|
|
|
|
<p>Note that in some cases, certain methods return status values without
|
|
issuing an exception. This occurs in situations that are not normally
|
|
considered an error, but when some informational status is returned. For
|
|
example, <a href="../../../com/sleepycat/je/Database.html#get-com.sleepycat.je.Transaction-com.sleepycat.je.DatabaseEntry-com.sleepycat.je.DatabaseEntry-com.sleepycat.je.Get-com.sleepycat.je.ReadOptions-"><code>Database.get</code></a> returns <a href="../../../com/sleepycat/je/OperationStatus.html#NOTFOUND"><code>OperationStatus.NOTFOUND</code></a> when a
|
|
requested key does not appear in the database.</p></div>
