Enum TransactionState

    • Enum Constant Detail

      • ABORTED_UNKNOWN

        public static final TransactionState ABORTED_UNKNOWN
        State used when a transaction was aborted with an unknown result. For example, failure to commit, rollback, or prepare due to broken connections (IO errors, or the connection already being closed).

        In most cases, the transaction is probably rolled back, but we're not sure. For example, the commit could have been received and processed by the server, but a subsequent connection failure occurred before the response was received. Similar for a transaction prepare (first step of two-phase commit).

        There are no valid transitions to and from this state; it can only be forcibly set.

        Since:
        5.0.13

    • 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​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • isValidTransition

        public final boolean isValidTransition​(TransactionState toState)
        Is the transition to toState valid from this state.
        Parameters:
        toState - The next state
        Returns:
        true transition is valid

      • validTransitionSet

        public final java.util.Set<TransactionState> validTransitionSet()
        Returns:
        Set of valid transitions from this state
