<h1>Description</h1>
<p>
Get/set the return value from the <a href="../../api_java/DbLockTab/open.html">DbLockTab.open</a> method, used if locking
is required for the file being opened (as is the case when multiple
processes or threads are accessing the same file).
If no value is set, no locking is done by the Berkeley DB access methods.
<p>
If both locking and transactions are being performed, the transaction
ID will be used as the locker ID.
If only locking is being performed, <a href="../../api_java/Db/open.html">Db.open</a> will acquire a
locker ID from <a href="../../api_java/DbLockTab/id.html">DbLockTab.id</a> and will use it for all locks required
for this instance of <a href="../../api_java/Db/open.html">Db.open</a>.
