Member Function Documentation

ReadAll()

std::string engine::io::BufferedReader::ReadAll	(	size_t	num_bytes,
		Deadline	deadline = {} )

Reads the exact number of bytes from the input stream.

Note

May return less bytes than requested in case of EOF.

ReadLine()

std::string engine::io::BufferedReader::ReadLine

(

Deadline

deadline = {}

)

Reads a line from the input, skipping empty lines.

Note

Does not return line terminators.

ReadUntil()

std::string engine::io::BufferedReader::ReadUntil	(	utils::function_ref< bool(int) const >	pred,
		Deadline	deadline = {} )

Reads the stream until the predicate returns true.

Parameters

pred	predicate that will be called for each byte read and EOF.
