T - The type of object to serialize.

All Implemented Interfaces:

StreamingDeserializer<T>, StreamingSerializer<T>, StreamingSerializerDeserializer<T>

public final class FixedLengthStreamingSerializer<T>
extends Object
implements StreamingSerializerDeserializer<T>

A StreamingSerializerDeserializer that uses a SerializerDeserializer and frames each object by preceding it with the length in bytes. The length component is fixed and always consumes 4 bytes.
