      • OPEN

        public static final Transaction.State OPEN
        When a transaction is in the `OPEN` state, messages can be produced and acked with this transaction. When a transaction is in the `OPEN` state, it can commit or abort.

      • COMMITTING

        public static final Transaction.State COMMITTING
        When a client invokes a commit, the transaction state is changed from `OPEN` to `COMMITTING`.

      • ABORTING

        public static final Transaction.State ABORTING
        When a client invokes an abort, the transaction state is changed from `OPEN` to `ABORTING`.

      • COMMITTED

        public static final Transaction.State COMMITTED
        When a client receives a response to a commit, the transaction state is changed from `COMMITTING` to `COMMITTED`.

      • ABORTED

        public static final Transaction.State ABORTED
        When a client receives a response to an abort, the transaction state is changed from `ABORTING` to `ABORTED`.

      • ERROR

        public static final Transaction.State ERROR
        When a client invokes a commit or an abort, but a transaction does not exist in a coordinator, then the state is changed to `ERROR`. When a client invokes a commit, but the transaction state in a coordinator is `ABORTED` or `ABORTING`, then the state is changed to `ERROR`. When a client invokes an abort, but the transaction state in a coordinator is `COMMITTED` or `COMMITTING`, then the state is changed to `ERROR`.

      • TIME_OUT

        public static final Transaction.State TIME_OUT
        When a transaction is timed out and the transaction state is `OPEN`, then the transaction state is changed from `OPEN` to `TIME_OUT`.

    • 方法详细资料

      • values

        public static Transaction.State[] values()
        按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: 
        for (Transaction.State c : Transaction.State.values())
    System.out.println(c);
        返回:
        按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

      • valueOf

        public static Transaction.State valueOf​(java.lang.String name)
        返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
        参数:
        name - 要返回的枚举常量的名称。
        返回:
        返回带有指定名称的枚举常量
        抛出:
        java.lang.IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量
        java.lang.NullPointerException - 如果参数为空值
