The LineIO class implements a line-orient interface for TCP sockets. It’s a specialization of sockio. This class is intended for line-oriented protocols.
Creates a new LineIO object
The socket which will be used
The size of the buffer to use (default is 8192)
# File lib/network/lineio.rb, line 27 def initialize(sock, bufsize=8192) super(sock,bufsize) end
read will receive a set of lines from the socket. A line may be terminated by CRLF, CRNUL, LFCR, CR, or LF. Not yet terminated lines are left in the @inbuffer.
One or more complete lines or nil.
A sockets error occurred.
The connection has closed normally.
