Examples of java.io.LineNumberReader.readLine()

java.io.LineNumberReader.readLine()
Answers a String representing the next line of text available in this LineNumberReader. A line is represented by 0 or more characters followed by '\n', '\r', "\n\r" or end of stream. The String does not include the newline sequence. @return String the contents of the line or null if no characters wereread before end of stream. @throws IOException If the LineNumberReader is already closed or some other IO error occurs.
