/**
* {@link ConfigurablePropertyAccessor} implementation that directly accesses
* instance fields. Allows for direct binding to fields instead of going through
* JavaBean setters.
*
* <p>As of Spring 4.2, the vast majority of the {@link BeanWrapper} features have
* been merged to {@link AbstractPropertyAccessor}, which means that property
* traversal as well as collections and map access is now supported here as well.
*
* <p>A DirectFieldAccessor's default for the "extractOldValueForEditor" setting
* is "true", since a field can always be read without side effects.
