EditorDelegate (Google Web Toolkit Javadoc)

Type Parameters:
T - the type of object the delegate can accept

All Known Implementing Classes:

MockEditorDelegate
```
public interface EditorDelegate<T>
```
Binds an individual Editor to the backing service. Every Editor has a peer EditorDelegate. If an Editor implements the ValueAwareEditor interface, the EditorDriver will make the delegate available through the HasEditorDelegate.setDelegate(com.google.gwt.editor.client.EditorDelegate<T>) method.

Method Summary

Methods
Modifier and Type	Method and Description
`java.lang.String`	`getPath()` Returns the Editor's path, relative to the root object.
`void`	`recordError(java.lang.String message, java.lang.Object value, java.lang.Object userData)` This method should be called from `ValueAwareEditor.flush()` or `TakesValue.getValue()` to record an error that will be reported to the nearest super-Editor that implements the `HasEditorErrors` interface.
`void`	`setDirty(boolean dirty)` Toggle the dirty-state flag for the Editor.
`HandlerRegistration`	`subscribe()` Register for notifications if object being edited is updated.

- Method Detail
  - getPath
```
java.lang.String getPath()
```
    Returns the Editor's path, relative to the root object.
    
    Returns:
    the path as a String
  - recordError
```
void recordError(java.lang.String message,
               java.lang.Object value,
               java.lang.Object userData)
```
    This method should be called from ValueAwareEditor.flush() or TakesValue.getValue() to record an error that will be reported to the nearest super-Editor that implements the HasEditorErrors interface.
    
    Parameters:
    message - a textual description of the error
    value - the value to be returned by EditorError.getValue() or null if the value currently associated with the Editor should be used
    userData - an arbitrary object, possibly null, that can be retrieved with EditorError.getUserData()
  - setDirty
```
void setDirty(boolean dirty)
```
    Toggle the dirty-state flag for the Editor.
    The dirty state of an Editor will be automatically cleared any time the Driver's edit() or flush() methods are called.
    The dirty state will be automatically calculated for LeafValueEditor instances based on an Object.equals(Object) comparison of TakesValue.getValue() and the value last passed to TakesValue.setValue(Object), however a clean state can be overridden by calling setDirty(true).
    
    Parameters:
    dirty - the dirty state of the Editor
  - subscribe
```
HandlerRegistration subscribe()
```
    Register for notifications if object being edited is updated. Not all backends support subscriptions and will return null.
    The notification will occur via ValueAwareEditor.onPropertyChange(java.lang.String...) if the backend supports in-place property updates, otherwise updates will be passed via ValueAwareEditor.setValue(T).
    
    Returns:
    a HandlerRegistration to unsubscribe from the notifications or null if the delegate does not support subscription
