Class HashMapEntries

java.lang.Object

io.lacuna.bifurcan.durable.blocks.HashMapEntries

public class HashMapEntries
extends java.lang.Object

A block that represents zero or more key/value pairs in a HashMap.

Encoding: - the number of preceding entries [VLQ] - the hash for each entry [HashDeltas] - keys [an ENCODED block generated by IDurableEncoding.Map#keyEncoding()] - values [an ENCODED block generated by IDurableEncoding.Map#valueEncoding()
