| /** |
| * Base class for all transaction related exceptions. |
| * In case of {@link org.apache.ignite.cache.CacheAtomicityMode#TRANSACTIONAL} cache - |
| * any method throwing this or nested exception have transactional behaviour |
| * (it can be rolled back and not seen outside transaction before committed). |
| * In case of {@link org.apache.ignite.cache.CacheAtomicityMode#ATOMIC} cache - every action is committed when it done. |
| * <p> |
| * Before doing main thing, all transactional methods (commit, rollback and close) must obtain a readLock from |
| * context's gateway to prevent simultaneous actions which can break result of transaction. |
| * |
| * Then method delegates action to internal transaction representation which can fail in some cases and throw exception. |
| * |
| * Anyway, if there is success or fail, method must free gateway lock. |
| * <p> |
| * {@link TransactionDeadlockException} If deadlock detected within transaction. |
| * {@link TransactionHeuristicException} If operation performs within transaction that entered an unknown state. |
| * {@link TransactionOptimisticException} If operation with optimistic behavior failed. |
| * {@link TransactionRollbackException} If operation performs within transaction that automatically rolled back. |
| * {@link TransactionTimeoutException} If operation performs within transaction and timeout occurred. |
| * {@link TransactionSerializationException} If operation performs within mvcc transaction and write conflict occurred. |
