Class ToNetASCIIInputStream


public final class ToNetASCIIInputStream
extends FilterInputStream

This class wraps an input stream, replacing all singly occurring <LF> (linefeed) characters with <CR><LF> (carriage return followed by linefeed), which is the NETASCII standard for representing a newline. You would use this class to implement ASCII file transfers requiring conversion to NETASCII.
