class FArchiveFileReaderGeneric : public FArchive

Type	Name	Description
bool	bFirstReadAfterSeek
TArray64< uint8 >	BufferArray	The contract for the BufferWindow and the low level pos is that if we have a BufferWindow and Pos is within it, then the LowLevel Pos is at the end of the BufferWindow If we do not have a BufferWindow, or Pos is outside of it, then LowLevel Pos is at Pos.
int64	BufferBase
int64	BufferSize
FString	Filename	Filename for debugging purposes.
uint32	Flags
TUniquePtr< IFileHandle >	Handle
int64	Pos
int64	Size

	Type	Name	Description
		FArchiveFileReaderGeneric ( IFileHandle* InHandle, const TCHAR* InFilename, int64 InSize, uint32 InBufferSize, uint32 InFlags )

	Type	Name	Description
		~FArchiveFileReaderGeneric ()

Type	Name	Description
void	CloseLowLevel ()	Close the file handle
bool	InternalPrecache ( int64 PrecacheOffset, int64 PrecacheSize )
bool	IsSilent ()	Returns true if the archive should suppress logging in case of error
void	ReadLowLevel ( uint8* Dest, int64 CountToRead, int64& OutBytesRead )	Platform specific read
bool	SeekLowLevel ( int64 InPos )	Platform specific seek

Type	Name	Description
bool	Close ()	Attempts to close and finalize any handles used for backing data storage, returns true if it succeeded.
void	FlushCache ()	Flushes cache and frees internal data.
bool	Precache ( int64 PrecacheOffset, int64 PrecacheSize )	Hint the archive that the region starting at passed in offset and spanning the passed in size is going to be read soon and should be precached.
void	Seek ( int64 InPos )	Attempts to set the current offset into backing data storage, this will do nothing if there is no storage.
void	Serialize ( void* V, int64 Length )

Type	Name	Description
FString	GetArchiveName ()	Returns the name of the Archive.
int64	Tell ()	Returns the current location within the backing data storage, which can possibly be passed to Seek later to restore a read/write location.
int64	TotalSize ()	Returns total size of the backing data storage.
