CacheAnswer

What a HeldCodes stream's writer needs to hear (FJoinStreamWriter::TakeHeldCodes): U64 the head's FileHash, U32 the index's tile count, then one bit a tile in index order, lowest bit first, set when the joiner holds its code.

Declaration

const std::vector<uint8_t>& CacheAnswer() const;

Header: #include "Native/Net/NetJoin.h"
Module: PublicDependencyModuleNames.Add("OrreryTerrainCore"); in your module’s Build.cs.
Stability: Experimental: supported, may change in a minor version, with a changelog line.
Thread: Feed, TakeDrain, TakeCacheFill and ResidentBytes on one thread (the game thread); Drain on any thread, one call at a time; the file is thread-safe, for the page jobs. (the rule of FJoinStreamReader)

Description

Empty until CacheFilled, and for any other stream.
