Usage

From source file:com.abiquo.server.core.cloud.VirtualMachineDAO.java

public void refreshLock(final VirtualMachine vm) {
    // We force the refresh from database (PESSIMISTIC) and increment the version of the object
    // (INCREMENT) to ensure that no other code will be using the "unlocked" object.
    getEntityManager().refresh(vm, LockModeType.PESSIMISTIC_FORCE_INCREMENT);
}
