Enum TimeDomain

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<TimeDomain>
    @Experimental(TIMERS)
public enum TimeDomain
extends java.lang.Enum<TimeDomain>
    TimeDomain specifies whether an operation is based on timestamps of elements or current "real-world" time as reported while processing.

      Modifier and Type Method Description
      static TimeDomain valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name.
      static TimeDomain[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.

      • EVENT_TIME

        public static final TimeDomain EVENT_TIME
        The EVENT_TIME domain corresponds to the timestamps on the elements. Time advances on the system watermark advances.

      • PROCESSING_TIME

        public static final TimeDomain PROCESSING_TIME
        The PROCESSING_TIME domain corresponds to the current (system) time. This is advanced during execution of the pipeline.

      • SYNCHRONIZED_PROCESSING_TIME

        @Internal
public static final TimeDomain SYNCHRONIZED_PROCESSING_TIME
        For internal use only; no backwards compatibility guarantees.

        Same as the PROCESSING_TIME domain, except it won't fire a timer set for time t until all timers from earlier stages set for a time earlier than t have fired.

      • values

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

      • valueOf

        public static TimeDomain 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
