FJoinCache

A save a client kept from an earlier join, opened for a later join to take bytes from: its index by code hash.

Declaration

class FJoinCache

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: Tier 1, immutable once open; the file must be thread-safe, as every ITerrainSaveFile.

Description

Nothing in it is trusted. A join takes a code only when its bytes hash to what the server's index says, and a whole save only when the server's head names its FileHash, and every byte is still hashed at the join's last check.

Tier 1, immutable once open; the file must be thread-safe, as every ITerrainSaveFile.
