<p>
When you abort a transaction, all database
<span>
or store
</span>
modifications performed
under the protection of the transaction are discarded, and all
locks currently held by the transaction are released. In this event,
your data is simply left in the
state that it was in before the transaction began performing data
modifications.
</p>
<p>
Once you have aborted a transaction, the transaction
handle that you used for the transaction is no longer valid. To
perform database activities under the control of a new
transaction, you must obtain a fresh transactional handle.
</p>
<p>
To abort a transaction, call
<span><code class="methodname">Transaction.abort()</code>.</span>
