Enum DataInputStatus

  • All Implemented Interfaces:
    Serializable, Comparable<DataInputStatus>
    @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 Detail

      • 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 Detail

      • values

        public static DataInputStatus[] 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 (DataInputStatus c : DataInputStatus.values())
    System.out.println(c);
        Returns:
        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:
        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
