This class is a FilterInputStream that keeps track of the number of lines of data that have been read. getLineNumber( ) returns the current line number; setLineNumber( ) sets the line number of the current line. Subsequent lines are numbered starting from that number. This class is deprecated as of Java 1.1 because it does not properly convert bytes to characters. Use LineNumberReader instead.
