  Type Name Description
Public class UClass NotPlaceable Transient AReplicationGraphDebugActor -----------------------------------------------------------------------------------------------------------------------------------------  
Public struct FActorConnectionPair Debug Actor/Connection pair that can be set by code for further narrowing down breakpoints/logging.  
Public struct FActorRepList The actual underlying list type that the system uses for a list of replicated actors.  
Public struct FActorRepListConstView Gives temporary read-only access to a FActorRepListRefView by holding a reference to it.  
Public struct FActorRepListRefView Holds a list of replicated actors that can be added/removed to.  
Public struct FActorRepListStatCollector This struct will passed to all nodes in the repgraph and collect information on every ActorRepList

Public struct FConnectionReplicationActorInfo Per-Actor data that is stored per connection  
Public struct FFastSharedReplicationInfo    
Public struct FGatheredReplicationActorLists This represents "the list of gathered actors". This is what we push down the Replication Graph and nodes will either Push/Pop List Categories or will add their Replication Lists.

Public struct FPerConnectionActorInfoMap Map for Actor -> ConnectionActorInfo.  
Public struct FPrioritizedActorDebugInfo    
Public struct FPrioritizedActorFullDebugDetails -----------------------------------------------------------------------------------------------------------------------------------------Prioritized Actor Lists  
Public struct FPrioritizedRepList Prioritized List of actors to replicate. This is what we actually use to replicate actors.  
Public struct FRenamedReplicatedActorInfo -----------------------------------------------------------------------------------------------------------------------------------------RenamedReplicatedActorInfo  
Public struct FRepGraphConnectionSaturationAnalytics    
Public struct FReplicationGraphCSVTracker Helper struct for tracking finer grained ReplicationGraph stats through the CSV profiler.  
Public struct FReplicationGraphDebugInfo -----------------------------------------------------------------------------------------------------------------------------------------Debug Info  
Public struct FReplicationGraphDestructionSettings -----------------------------------------------------------------------------------------------------------------------------------------  
Public struct FReplicationGraphGlobalData Data that every replication graph has access to/is initialized with  
Public class FReplicationGraphModule Module definition for replication graph  
Public struct FRPCSendPolicyInfo -----------------------------------------------------------------------------------------------------------------------------------------RPCs  
Public struct FSkippedActorFullDebugDetails Debug data about an actor that was skipped during the prioritization phase  
Public struct FStreamingLevelActorListCollection -----------------------------------------------------------------------------------------------------------------------------------------Level based actor lists  
Public struct UStruct FTearOffActorInfo    
Public struct TActorRepListViewBase This is a base templated type for the list "Views".  
Public struct TClassMap Templatd struct for mapping UClasses to some data type.  
Public class UClass Transient, Config UBasicReplicationGraph A basic implementation of replication graph.

Public class UClass UReplicationGraphNode_ActorListFrequencyBuckets A Node that contains ReplicateActorLists.  
Public class UClass UReplicationGraphNode_AlwaysRelevant    
Public class UClass UReplicationGraphNode_AlwaysRelevant_ForConnection Adds actors that are always relevant for a connection.  
Public class UClass UReplicationGraphNode_ConnectionDormancyNode Removes dormant (on connection) actors from its rep lists  
Public class UClass UReplicationGraphNode_DormancyNode Stores per-connection copies of a main actor list.  
Public class UClass UReplicationGraphNode_DynamicSpatialFrequency A node intended for dynamic (moving) actors where replication frequency is based on distance to the connection's view location  
Public class UClass UReplicationGraphNode_GridCell    
Public class UClass UReplicationGraphNode_GridSpatialization2D    
Public class UClass UReplicationGraphNode_TearOff_ForConnection Manages actors that are Tear Off.

Enums

  Type Name Description
Public enum EActorRepListTypeFlags Generic flags that describe an actor list. Currently only used for "Default" vs "FastShared" path. These are for unsorted lists that are returned from the graph, merged together, sorted, and finally replicated until bandwidth limit is hit.
