Method Details

deserialize

public Double deserialize(String topic,
 byte[] data)

Description copied from interface: Deserializer

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

Specified by:

deserialize in interface Deserializer<Double>

Parameters:

topic - topic associated with the data

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

public Double deserialize(String topic,
 Headers headers,
 ByteBuffer data)

Description copied from interface: Deserializer

Deserialize a record value from a ByteBuffer into a value or object.

If ByteBufferDeserializer is used by an application, the application code cannot make any assumptions about the returned ByteBuffer like the position, limit, capacity, etc., or if it is backed by an array or not.

Similarly, if this method is overridden, the implementation cannot make any assumptions about the passed in ByteBuffer either.

Specified by:

deserialize in interface Deserializer<Double>

Parameters:

topic - topic associated with the data

headers - 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
