All Implemented Interfaces:

java.io.Serializable

public class OptimisticLockException
extends java.lang.RuntimeException

An OptimisticLockException is thrown when trying to update or delete a row that has been changed since last read from the database. OptimisticLockException is a runtime exception because optimistic locking is turned off by default, and as such will never be thrown in a default configuration. In order to turn on optimistic locking, you need to specify the version column in your TableQuery instance.
