Constructor & Destructor Documentation

◆ SystemFileStream() [1/2]

AZ::IO::SystemFileStream::SystemFileStream ( )

Creates a SystemFile stream with an underlying SystemFile which is not open The Open() function can be used to Open the SystemFile

◆ SystemFileStream() [2/2]

AZ::IO::SystemFileStream::SystemFileStream	(	SystemFile &&	file,
		OpenMode	mode
	)

For this overload, the mode parameter is for passing the mode flags used to open the supplied SystemFile This purpose of the mmode parameter is only for use in the ReOpen() function to determine how to reopen the SystemFile
