Package io.datarouter.bytes.kvfile.codec

Class KvFileBlockCodec<T>

java.lang.Object

io.datarouter.bytes.kvfile.codec.KvFileBlockCodec<T>

All Implemented Interfaces:

Codec<List<T>,byte[]>

public class KvFileBlockCodec<T>
extends Object
implements Codec<List<T>,byte[]>

Translates a List of user-provided items to a byte[]. Intended for use in Blockfiles of Kvs. Use the identity() method for things like merging Kvs from multiple files without decoding to the user-provided type.
