K - The type of the keys in the map.V - The type of the values in the map.@Internal public final class HashMapSerializer<K,V> extends TypeSerializer<HashMap<K,V>>
HashMap. The serializer relies on a key serializer and a value serializer
for the serialization of the map's key-value pairs.
The serialization format for the map is as follows: four bytes for the length of the map, followed by the serialized representation of each key-value pair. To allow null values, each value is prefixed by a null marker.
