Method Detail

deserialize

public T deserialize(String topic,
                     Headers headers,
                     byte[] data)

Description copied from interface: ExtendedDeserializer

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

Specified by:

deserialize in interface Deserializer<T>

Specified by:

deserialize in interface ExtendedDeserializer<T>

Parameters:

topic - topic associated with the data

headers - headers associated with the record; may be empty.

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

Parameters:

configs - configs in key/value pairs

isKey - whether is for key or value
