20: * <p>{@link BeanUtilsBean} implementation that creates a
21: * {@link ConvertUtilsBean2} and delegates conversion to
22: * {@link ConvertUtilsBean#convert(Object, Class)}.
23: * </p>
24: *
25: * <p>
26: * To configure this implementation for the current context ClassLoader invoke
27: * <code>BeanUtilsBean.setInstance(new BeanUtilsBean2());</code>
28: * </p>
29: *
30: * <p>
31: * BeanUtils 1.7.0 delegated all conversion to String to the converter
32: * registered for the <code>String.class</code>. One of the improvements in
33: * BeanUtils 1.8.0 was to upgrade the {@link Converter} implementations so
34: * that they could handle conversion to String for their type (e.g.
35: * IntegerConverter now handles conversion from an Integer to a String as
36: * well as String to Integer).
37: * </p>
38: *
39: * <p>
40: * In order to take advantage of these improvements BeanUtils needs to change
41: * how it gets the appropriate {@link Converter}. This functionality has been
42: * implemented in the new {@link ConvertUtilsBean#lookup(Class, Class)} and
43: * {@link ConvertUtilsBean#convert(Object, Class)} methods. However changing
44: * {@link BeanUtilsBean} to use these methods could create compatibility
45: * issues for existing users. In order to avoid that, this new
46: * {@link BeanUtilsBean} implementation has been created (and the associated
47: * {@link ConvertUtilsBean2}).
