/**
 * 

{@link BeanUtilsBean} implementation that creates a * {@link ConvertUtilsBean2} and delegates conversion to * {@link ConvertUtilsBean#convert(Object, Class)}. *

* *

* To configure this implementation for the current context ClassLoader invoke * {@code BeanUtilsBean.setInstance(new BeanUtilsBean2());} *

* *

* BeanUtils 1.7.0 delegated all conversion to String to the converter * registered for the {@code String.class}. One of the improvements in * BeanUtils 1.8.0 was to upgrade the {@link Converter} implementations so * that they could handle conversion to String for their type (e.g. * IntegerConverter now handles conversion from an Integer to a String as * well as String to Integer). *

* *

* In order to take advantage of these improvements BeanUtils needs to change * how it gets the appropriate {@link Converter}. This functionality has been * implemented in the new {@link ConvertUtilsBean#lookup(Class, Class)} and * {@link ConvertUtilsBean#convert(Object, Class)} methods. However changing * {@link BeanUtilsBean} to use these methods could create compatibility * issues for existing users. In order to avoid that, this new * {@link BeanUtilsBean} implementation has been created (and the associated * {@link ConvertUtilsBean2}). *

* * @see ConvertUtilsBean2 * @since 1.8.0 */ public class BeanUtilsBean2 extends BeanUtilsBean { /** *

Constructs an instance using new property * and conversion instances.

*/ public BeanUtilsBean2() { super(new ConvertUtilsBean2()); } /** *

Converts the value to an object of the specified class (if * possible).

* * @param value Value to be converted (may be null) * @param type Class of the value to be converted to * @return The converted value */ @Override protected Object convert(final Object value, final Class type) { return getConvertUtils().convert(value, type); } }
