  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 FCachedAlwaysRelevantActorInfo    
Public struct UStruct FClassReplicationInfo --------------------------------------------------------------------------------------------------------------------------------------  
Public struct UStruct FConnectionAlwaysRelevantNodePair    
Public struct FConnectionGatherActorListParameters Parameter structure for what we actually pass down during the Gather phase.  
Public struct FConnectionReplicationActorInfo Per-Actor data that is stored per connection  
Public struct FFastSharedReplicationInfo    
Public struct FGatheredReplicationActorLists This represents "the list of gathered lists". 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 FGlobalActorReplicationEvents    
Public struct FGlobalActorReplicationInfo Per-Actor data that is global for the entire Replication Graph  
Public struct FGlobalActorReplicationInfoMap    
Public struct UStruct FLastLocationGatherInfo -----------------------------------------------------------------------------------------------------------------------------------------  
Public struct FLevelBasedActorList Holds a list of actors grouped by the permanent level or their streaming level  
Public struct FNativeClassAccumulator    
Public struct FNewReplicatedActorInfo --------------------------------------------------------------------------------------------------------------------------------------  
Public struct FPerConnectionActorInfoMap Map for Actor -> ConnectionActorInfo.  
Public struct FPrioritizedActorDebugInfo    
Public struct FPrioritizedActorFullDebugDetails --------------------------------------------------------------------------------------------------------------------------------------  
Public struct FPrioritizedRepList Prioritized List of actors to replicate. This is what we actually use to replicate actors.  
Public struct FRepGraphConnectionSaturationAnalytics    
Public struct FReplicationGraphCSVTracker Helper struct for tracking finer grained ReplicationGraph stats through the CSV profiler.  
Public struct FReplicationGraphDebugInfo -----------------------------------------------------------------------------------------------------------------------------------------  
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 -----------------------------------------------------------------------------------------------------------------------------------------  
Public struct FSkippedActorFullDebugDetails Debug data about an actor that was skipped during the prioritization phase  
Public struct FStreamingLevelActorListCollection --------------------------------------------------------------------------------------------------------------------------------------  
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_ActorList A Node that contains ReplicateActorLists.  
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.  

Functions

  Type Name Description
Public function void  
Public function UClass *  
Public function FString  
Public function bool Tests if an actor is valid for replication: not pending kill, etc. Says nothing about wanting to replicate or should replicate, etc.
Public function bool Tests if an actor is valid for replication gathering. Meaning, it can be gathered from the replication graph and considered for replication.
