Represents an input stream with updating reading position. More...

Public Member Functions
virtual void	seek (std::streamoff offset, std::ios::seekdir seekDir)=0
	change reading position, a way of changing depends on seekDir parameter

virtual size_t	tell ()=0
	return current reading position

virtual bool	isEof ()=0
	returns true if end of stream has been reached

size_t	fileSize ()
	return size of the stream

Public Member Functions inherited from IInputStream
virtual size_t	read (char *dst, size_t size)=0
	Reads up to `size` bytes from stream. Blocking (waiting for new data) is allowed.

size_t	read (std::span< std::byte > destination)
	Reads up to `destination.size()` bytes from stream. Blocking (waiting for new data) is allowed.

void	readExact (char *dst, size_t size)
	Reads exact `size` bytes from stream. Blocking (waiting for new data) is allowed.
