Remarks

FNetDeltaSerializeInfo This is the parameter structure for delta serialization. It is kind of a dumping ground for anything custom implementations may need.

Variables

	Name	Description
bool	bCalledPreNetReceive	Whether or not PreNetReceive has been called on the owning object.
bool	bGuidListsChanged	Whether or not we changed Guid / Object references. Used when reading.
bool	bInternalAck	Whether or the connection is completely reliable.
bool	bIsWritingOnClient	Whether or not we're sending / writing data from the client.
bool	bOutHasMoreUnmapped	Whether or not there are still some outstanding unmapped objects referenced by the struct.
bool	bOutSomeObjectsWereMapped	If true, then we successfully mapped some unmapped objects.
bool	bSupportsFastArrayDeltaStructSerialization	Whether or not we support FFastArraySerializer::FastArrayDeltaSerialize_DeltaSerializeStructs
bool	bUpdateUnmappedObjects	If true, we are updating unmapped objects
UNetConnection ...	Connection	Connection that we're currently serializing data for.
uint16	CustomDeltaIndex
void *	Data	Pointer to the struct that we're serializing.
FString	DebugName	Debugging variables.
TSet< FNetworkG...	GatherGuidReferences	When non-null, this indicates that we're gathering Guid References.
UPackageMap ...	Map	PackageMap that can be used to serialize objects and track Guid References.
const FNetworkG...	MoveGuidToUnmapped	When non-null, this indicates the given Guid has become unmapped and any references to it should be updated.
INetSerializeCB...	NetSerializeCB	Pointer to a NetSerializeCB implementation that can be used when serializing.
TSharedPtr< INe...	NewState	SharedPtr to new base state created by NetDeltaSerialize. Used when writing.
UObject *	Object	The object that owns the struct we're serializing.
INetDeltaBaseSt...	OldState	Pointer to the previous base state. Used when writing.
FBitReader *...	Reader	Used when reading
UStruct *	Struct	Type of struct that we're serializing.
int32 *	TrackedGuidMemoryBytes	When we're gathering guid references, ny memory used to track Guids can be added to this.
FBitWriter *...	Writer	Used when writing
