<h1>Description</h1>
|
|
<p>This manual page describes the DbException class and how it is used
|
|
by the various Berkeley DB classes.
|
|
<p>Most methods in the Berkeley DB classes throw an exception when an error occurs.
|
|
A DbException object contains an informational string and an errno. The
|
|
errno can be obtained using <a href="../api_java/get_errno.html">DbException.get_errno</a>. Since DbException
|
|
inherits from the java.Exception, the string portion is available using
|
|
toString().
|
|
<p>Some methods may return non-zero 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="../api_java/db_get.html">Db.get</a>
|
|
returns DB_NOTFOUND when a requested key does not appear in the database.
