Class FitsLineAppender


  • public class FitsLineAppender
    extends java.lang.Object
    This class handles the writing of a card line. It keeps track of the position in the line and will limit it to 80 characters. A write will never cross the line border but a write when the line is at position 80 will start a new line.
