Functions

	Name	Description
void	CompareWith ( const TCHAR* InFilename, const int64 TotalHeaderSize, const TCHAR* CallstackCutoffTe..., const int32 MaxDiffsToLog, TMap< FName, FArchiveDiffStats >& ... )	Compares the contents of this archive with the package on disk. Dumps all differences to log.
bool	GenerateDiffMap ( const TCHAR* InFilename, int64 TotalHeaderSize, int32 MaxDiffsToFind, FArchiveDiffMap& OutDiffMap )	Generates a map of all differences between the package on disk and this file.
bool	IsIdentical ( const TCHAR* InFilename, int64 BufferSize, const uint8* BufferData )	Compares the specified file on disk with the provided buffer
bool	LoadPackageIntoMemory ( const TCHAR* InFilename, FPackageData& OutPackageData )	Helper function to load package contents into memory. Supports EDL packages.

void	PopDebugDataString()
void	PushDebugDataString ( const FName& DebugData )	Debug stack storage if you want to add data to the archive for usage further down the serialization stack this should be used in conjunction with the FScopeAddDebugData struct
void	Serialize ( void* Data, int64 Num )

Overridden from FArchiveState

		Name	Description
	FUObjectSeri...	GetSerializeContext()	Gets the current UObject serialization context for this archive.
