          public static final TransactionState PREPARING

      Transaction validating.

    - #### PREPARED

          public static final TransactionState PREPARED

      Transaction validation succeeded.

    - #### MARKED_ROLLBACK

          public static final TransactionState MARKED_ROLLBACK

      Transaction is marked for rollback.

    - #### COMMITTING

          public static final TransactionState COMMITTING

      Transaction commit started (validating finished).

    - #### COMMITTED

          public static final TransactionState COMMITTED

      Transaction commit succeeded.

    - #### ROLLING_BACK

          public static final TransactionState ROLLING_BACK

      Transaction rollback started (validation failed).

  - ### Method Detail

    - #### values

          public static TransactionState[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (TransactionState c : TransactionState.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static TransactionState valueOf​(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null

    - #### fromOrdinal

          @Nullable
          public static @Nullable TransactionState fromOrdinal​(int ord)

      Efficiently gets enumerated value from its ordinal.
      Parameters:
        `ord` - Ordinal value.
      Returns:
        Enumerated value or `null` if ordinal out of range.
