All Implemented Interfaces:

@Internal public enum DataInputStatus extends Enum<DataInputStatus>
It is an internal equivalent of InputStatus that provides additional non public statuses.

An InputStatus indicates the availability of data from an asynchronous input. When asking an asynchronous input to produce data, it returns this status to indicate how to proceed.

  • Enum Constant Details

    • MORE_AVAILABLE

      public static final DataInputStatus MORE_AVAILABLE
      Indicator that more data is available and the input can be called immediately again to produce more data.

    • NOTHING_AVAILABLE

      public static final DataInputStatus NOTHING_AVAILABLE
      Indicator that no data is currently available, but more data will be available in the future again.

    • END_OF_RECOVERY

      public static final DataInputStatus END_OF_RECOVERY
      Indicator that all persisted data of the data exchange has been successfully restored.

    • STOPPED

      public static final DataInputStatus STOPPED
      Indicator that the input was stopped because of stop-with-savepoint without drain.

    • END_OF_DATA

      public static final DataInputStatus END_OF_DATA
      Indicator that the input has reached the end of data.

    • END_OF_INPUT

      public static final DataInputStatus END_OF_INPUT
      Indicator that the input has reached the end of data and control events. The input is about to close.

  • Method Details

    • values

      public static DataInputStatus[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.

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

    • valueOf

      public static DataInputStatus 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:
