                                                     org.apache.kafka.common.serialization.Serde<V> valueSerde)

Construct a Serialized instance with the provided key and value Serdes. If the Serde params are null the default serdes defined in the configs will be used.

Type Parameters:

K - the key type

V - the value type

Parameters:

keySerde - keySerde that will be used to materialize a stream if not specified the default serdes defined in the configs will be used

valueSerde - valueSerde that will be used to materialize a stream if not specified the default serdes defined in the configs will be used

Returns:

a new instance of Serialized configured with the provided serdes

withKeySerde

public Serialized<K,V> withKeySerde(org.apache.kafka.common.serialization.Serde<K> keySerde)

Construct a Serialized instance with the provided key Serde. If the Serde params are null the default serdes defined in the configs will be used.

Parameters:

keySerde - keySerde that will be used to materialize a stream if not specified the default serdes defined in the configs will be used

Returns:

a new instance of Serialized configured with the provided key serde

withValueSerde

public Serialized<K,V> withValueSerde(org.apache.kafka.common.serialization.Serde<V> valueSerde)

Construct a Serialized instance with the provided value Serde. If the Serde params are null the default serdes defined in the configs will be used.

Parameters:

valueSerde - valueSerde that will be used to materialize a stream if not specified the default serdes defined in the configs will be used

Returns:

a new instance of Serialized configured with the provided key serde
