Class ConversionHelper

java.lang.Object
  com.blackbear.flatworm.ConversionHelper

public class ConversionHelper
extends java.lang.Object

The ConversionHelper was created to seperate formatting responsibility into a seperate class. This class also makes writing your own converter more of a reality by seperating type conversion from string formatting. String formatting has moved to a seperate class called Util.
