  +--superwaba.ext.xplat.io.LineReader

public class LineReader

extends java.lang.Object

Class that read lines ending with 0d0a (enter/linefeed) from a stream. Well, it skips all control-characters and assumes that the first one is the line breaker. This makes it suitable for either Windows or Linux end-of-line sequences.

Here's a sample:

 LineReader reader = new LineReader(new File("text.txt"));
 String line;
 while ((line = reader.readLine()) != null)
 {
    ... do whatever you want with the line.
 }
 

Since:
