Method Detail
-
configure
default void configure(Map<String,?> configs, boolean isKey)
Configure this class.- Parameters:
configs
- configs in key/value pairsisKey
- whether is for key or value
-
deserialize
T deserialize(String topic, byte[] data)
Deserialize a record value from a byte array into a value or object.- Parameters:
topic
- topic associated with the datadata
- 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
-
deserialize
default T deserialize(String topic, Headers headers, byte[] data)
Deserialize a record value from a byte array into a value or object.- Parameters:
topic
- topic associated with the dataheaders
- 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
-
deserialize
default T deserialize(String topic, Headers headers, ByteBuffer data)
Deserialize a record value from a ByteBuffer into a value or object.- Parameters:
topic
- topic associated with the dataheaders
- headers associated with the record; may be empty.data
- serialized ByteBuffer; 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
