Method Detail

deserialize

public Object deserialize(byte[] payload)
                   throws org.apache.kafka.common.errors.SerializationException

Deserializes the payload without including schema information for primitive types, maps, and arrays. Just the resulting deserialized object is returned.

This behavior is the norm for Decoders/Deserializers.

Parameters:

payload - serialized data

Returns:

the deserialized object

Throws:

org.apache.kafka.common.errors.SerializationException

deserialize

public Object deserialize(byte[] payload,
                          org.apache.avro.Schema readerSchema)
                   throws org.apache.kafka.common.errors.SerializationException

Just like single-parameter version but accepts an Avro schema to use for reading

Parameters:

payload - serialized data

readerSchema - schema to use for Avro read (optional, enables Avro projection)

Returns:

the deserialized object

Throws:

org.apache.kafka.common.errors.SerializationException

protected Object deserialize(boolean includeSchemaAndVersion,
                             String topic,

                             byte[] payload,
                             org.apache.avro.Schema readerSchema)
                      throws org.apache.kafka.common.errors.SerializationException

Throws:
