struct TFastArraySerializeHelper

Remarks

Helper struct that contains common methods / logic for standard Fast Array serialization and Delta Struct Fast Array serialization.

Variables

	Name	Description
SerializerType ...	ArraySerializer	The actual FFastArraySerializer struct we're serializing.
TArray< Type > ...	Items	Set of array elements we're serializing.
FNetDeltaSerial...	Parms	Cached DeltaSerialize params.
UScriptStruct &...	Struct	Array element type struct.

Functions

	Name	Description
void	BuildChangedAndDeletedBuffers ( TMap< int32, int32 >& NewIDToKeyMa..., const TMap< int32, int32 >* Ol..., TArray< FFastArraySerializer_FastAr..., TArray< int32, TInlineAllocator< 8 ... )	Iterates over the current set of properties, comparing their keys with our old state, to figure out which have changed and need to be serialized.
int32	CalcNumItemsForConsideration()	Calculates the number of Items that actually need to be written.
bool	ConditionalCreateNewDeltaState ( const TMap< int32, int32 >& OldIDT..., const int32 BaseReplicationKey )	Checks to see if the ArrayReplicationKey has changed, and if so creates a new DeltaState that is passed out to the caller.
void	ConditionalLogSerializerState ( const TMap< int32, int32 >* Ol... )	Conditionally logs the important state of the serializer. For debug purposes only.
void	ConditionalRebuildItemMap()	Conditionally rebuilds the ID to Index map for items.
void	PostReceiveCleanup ( FFastArraySerializerHeader& Header, TArray< int32, TInlineAllocator< 8 ..., TArray< int32, TInlineAllocator< 8 ..., GuidMapType& GuidMap )	Manages any cleanup work that needs to be done after receiving elements, such as looking for items that were implicitly deleted, removing all deleted items, firing off any PostReceive / PostDeleted events, etc.
bool	ReadDeltaHeader ( FFastArraySerializerHeader& Header )	Reads in a FFastArraySerializerHeader
void	WriteDeltaHeader ( FFastArraySerializerHeader& Header )	Writes out a FFastArraySerializerHeader
