public interface LineInputStream

LineInputStream supports reading CRLF terminated lines that contain only US-ASCII characters from an input stream. Provides functionality that is similar to the deprecated DataInputStream.readLine(). Expected use is to read lines as String objects from an IMAP/SMTP/etc. stream.
This class also supports UTF-8 data by calling the appropriate constructor. Or, if the System property mail.mime.allowutf8 is set to true, an attempt will be made to interpret the data as UTF-8, falling back to treating it as an 8-bit charset if that fails.
