configure

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

Description copied from interface: Deserializer

Configure this class.

Specified by:

configure in interface Deserializer<Inner>

Parameters:

configs - configs in key/value pairs

isKey - whether the deserializer is used for the key or the value

deserialize

public List<Inner> deserialize(String topic,
 byte[] data)

Description copied from interface: Deserializer

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

It is recommended to deserialize a null byte array to a null object.

Specified by:

deserialize in interface Deserializer<Inner>

Parameters:

topic - topic associated with the data

data - serialized bytes; may be null

Returns:

deserialized typed data; may be null

deserialize

public List<Inner> deserialize(String topic,
 Headers headers,
 byte[] data)

Description copied from interface: Deserializer

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

It is recommended to deserialize a null byte array to a null object.

Note that the passed in Headers may be empty, but never null. The implementation is allowed to modify the passed in headers, as a side effect of deserialization. It is considered best practice to not delete or modify existing headers, but rather only add new ones.

Specified by:

deserialize in interface Deserializer<Inner>

Parameters:

topic - topic associated with the data

headers - headers associated with the record

data - serialized bytes; may be null

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:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface Deserializer<Inner>
