Enum TransactionReadSentinelBehavior

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<TransactionReadSentinelBehavior>
    public enum TransactionReadSentinelBehavior
extends java.lang.Enum<TransactionReadSentinelBehavior>
    This enum handles the different behaviors that can happen as a result of doing reads before the unreadable timestamp.

      • THROW_EXCEPTION

        public static final TransactionReadSentinelBehavior THROW_EXCEPTION
        Throw an exception when a sentinel is read. This is the default value.

      • IGNORE

        public static final TransactionReadSentinelBehavior IGNORE
        Ignore the sentinel read, and pretend that there is no value for this cell. This should only be used internally for special long running transactions.

      • values

        public static TransactionReadSentinelBehavior[] 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 (TransactionReadSentinelBehavior c : TransactionReadSentinelBehavior.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static TransactionReadSentinelBehavior 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
