public enum PunctuationType extends Enum<PunctuationType>
Controls what notion of time is used for punctuation scheduled viaProcessorContext.schedule(Duration, PunctuationType, Punctuator)
schedule}:- STREAM_TIME - uses "stream time", which is advanced by the processing of messages
in accordance with the timestamp as extracted by the
TimestampExtractor
in use. NOTE: Only advanced if messages arrive - WALL_CLOCK_TIME - uses system time (the wall-clock time),
which is advanced at the polling interval (
StreamsConfig.POLL_MS_CONFIG
) independent of whether new messages arrive. NOTE: This is best effort only as its granularity is limited by how long an iteration of the processing loop takes to complete

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

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 nameNullPointerException
- if the argument is null
