Public struct

FReplicatedActorProperty

Struct containing property and offset for replicated actor properties

Public class

FReplicationChangelistMgr

FReplicationChangelistMgr manages a list of change lists for a particular replicated object that have occurred since the object started replicating Once the history is completely full, the very first changelist will then be merged with the next one (freeing a slot) This way we always have the entire history for join in progress players This information is then used by all connections, to share the compare work needed to determine what to send each connection Connections will send any changelist that is new since the last time the connection checked
