Nice Move With ValueSetter

I've been working on software architecture refactoring for last couple weeks. During a workshop one of architects showed me an interesting approach.

We were applying MVP-like style and then faced with the question: How a Presenter should tell a View to change its state?

Brute force approach looks like following:

public class Presenter { private View view; public void doSomething() {//Here, services are processing something really important view.setTitle( "Updated" ); view.setName( "New name" ); }}public class Form extends JFrame implements View { private JTextfield nameTf; @Override public void setTitle( String title ) {  setTitle( title ); } @Override public void setName( String name ) {  nameTf.setText( name ); }}

public abstract class ValueSetter {private static Map<Class<?>, ValueSetter> SETTERS; static {  SETTERS = new HashMap<Class<?>, ValueSetter>();  SETTERS.put(JTextField.class, new JTextFieldSetter()); } public static ValueSetter get( Class<?> type ) {  if( SETTERS.containsKey(type) ) {   return SETTERS.get(type);  }  throw new IllegalArgumentException( "Missing ValueSetter for " + type ); } public abstract void set( Object target, Object value ); private static class JTextFieldSetter extends ValueSetter {  @Override  public void set(Object target, Object value) {   ((JTextField)target).setText( (String) value );  } } private static class JFrameSetter extends ValueSetter {  @Override  public void set(Object target, Object value) {   ((JFrame)target).setTitle( (String) value );  } }}

public class Form extends JForm implements View { private Map<String, JComponent> components; @Override public void updateComponent(String id, Object value) {  JComponent component = components.get(id);  ValueSetter.get(component.getClass()).set(component, value);   }}
