Class TimeWindowedDeserializer<T>

java.lang.Object

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

All Implemented Interfaces:

Closeable, AutoCloseable, Deserializer<Windowed<T>>

public class TimeWindowedDeserializer<T>
extends Object
implements Deserializer<Windowed<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.

configure

public void configure(Map<String,?> configs,
                      boolean isKey)

Description copied from interface: Deserializer

Configure this class.

Specified by:

configure in interface Deserializer<Windowed<T>>

Parameters:

configs - configs in key/value pairs

isKey - whether is for key or value

deserialize

public Windowed<T> deserialize(String topic,
                               byte[] data)

Description copied from interface: Deserializer

Deserialize a record value from a byte array into a value or object.

Specified by:

deserialize in interface Deserializer<Windowed<T>>

Parameters:

topic - topic associated with the data

data - serialized bytes; may be null; implementations are recommended to handle null by returning a value or null rather than throwing an exception.

Returns:

deserialized typed data; may be null

close

public void close()

Description copied from interface: Deserializer

Close this deserializer.

This method must be idempotent as it may be called multiple times.

Specified by:

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Deserializer<Windowed<T>>

setIsChangelogTopic

public void setIsChangelogTopic(boolean isChangelogTopic)
