Examples of com.sleepycat.je.Transaction.abort()

com.sleepycat.je.Transaction.abort()
Cause an abnormal termination of the transaction.
The log is played backward, and any necessary undo operations are done. Before Transaction.abort returns, any locks held by the transaction will have been released.

In the case of nested transactions, aborting a parent transaction causes all children (unresolved or not) of the parent transaction to be aborted.

All cursors opened within the transaction must be closed before the transaction is aborted.

After this method has been called, regardless of its return, the {@link Transaction} handle may not be accessed again, with oneexception: the {@code abort} method itself may be called any number oftimes to simplify error handling.
@throws EnvironmentFailureException if an unexpected, internal orenvironment-wide failure occurs. @throws IllegalStateException if the environment has been closed, orcursors associated with the transaction are still open.
