Package com.illumon.util.codec

Class MapCodec<K,V>

java.lang.Object

com.illumon.util.codec.MapCodec<K,V>

All Implemented Interfaces:

ObjectCodec<Map<K,V>>, io.deephaven.util.codec.ObjectCodec<Map<K,V>>, io.deephaven.util.codec.ObjectDecoder<Map<K,V>>

Direct Known Subclasses:

StringBooleanMapCodec

public abstract class MapCodec<K,V>
extends Object
implements ObjectCodec<Map<K,V>>

ObjectCodec implementation for Maps of type K to V. Each map is encoded as an integer length, followed by encoded pairs of key values. A null map is represented as an array of zero bytes.
