• getPropertyAccessor

  public abstract ConfigurablePropertyAccessor getPropertyAccessor()

  Provide the PropertyAccessor to work with, according to the concrete strategy of access.

  Note that a PropertyAccessor used by a BindingResult should always have its "extractOldValueForEditor" flag set to "true" by default, since this is typically possible without side effects for model objects that serve as data binding target.
