All Implemented Interfaces:

AdapterNode, Element, Node

public class BeanAdapter
extends AbstractAdapterElement

This class is the most general type of adapter, utilizing reflective introspection to present a DOM view of all of the public properties of its value. For example, a property returning a JavaBean such as:

 public Person getMyPerson() { ... }
 ...
 class Person {
      public String getFirstName();
      public String getLastName();
 }
 

would be rendered as: ... ...
