Enum PunctuationType

java.lang.Object

java.lang.Enum<PunctuationType>

org.apache.kafka.streams.processor.PunctuationType

All Implemented Interfaces:

Serializable, Comparable<PunctuationType>

public enum PunctuationType
extends Enum<PunctuationType>

Controls what notion of time is used for punctuation scheduled via ProcessorContext.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

Method Detail

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

public static PunctuationType 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
