/**
 * {@link ConfigurablePropertyAccessor} implementation that directly accesses
 * instance fields. Allows for direct binding to fields instead of going through
 * JavaBean setters.
 *
 * 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.
 *
 * A DirectFieldAccessor's default for the "extractOldValueForEditor" setting
 * is "true", since a field can always be read without side effects.
