Class TimeWindowedSerializer<T>

java.lang.Object

org.apache.kafka.streams.kstream.TimeWindowedSerializer<T>

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, Serializer<Windowed<T>>, org.apache.kafka.streams.kstream.internals.WindowedSerializer<T>

public class TimeWindowedSerializer<T>
extends java.lang.Object
implements org.apache.kafka.streams.kstream.internals.WindowedSerializer<T>

The inner serde class can be specified by setting the property StreamsConfig.DEFAULT_WINDOWED_KEY_SERDE_INNER_CLASS or StreamsConfig.DEFAULT_WINDOWED_VALUE_SERDE_INNER_CLASS if the no-arg constructor is called and hence it is not passed during initialization.
