```
    Description copied from interface: EditorContext
    
    Returns a non-null value if the editor returned by EditorContext.getEditor() implements HasEditorDelegate.
    
    Specified by:
    
    asHasEditorDelegate in interface EditorContext<T>
  - asHasEditorErrors
```
public HasEditorErrors<T> asHasEditorErrors()
```
    Description copied from interface: EditorContext
    
    Returns a non-null value if the editor returned by EditorContext.getEditor() implements HasEditorErrors.
    
    Specified by:
    
    asHasEditorErrors in interface EditorContext<T>
  - asLeafValueEditor
```
public LeafValueEditor<T> asLeafValueEditor()
```
    Description copied from interface: EditorContext
    
    Returns a non-null value if the editor returned by EditorContext.getEditor() implements LeafValueEditor.
    
    Specified by:
    
    asLeafValueEditor in interface EditorContext<T>
  - asValueAwareEditor
```
public ValueAwareEditor<T> asValueAwareEditor()
```
    Description copied from interface: EditorContext
    
    Returns a non-null value if the editor returned by EditorContext.getEditor() implements ValueAwareEditor.
    
    Specified by:
    
    asValueAwareEditor in interface EditorContext<T>
  - canSetInModel
```
public abstract boolean canSetInModel()
```
    Description copied from interface: EditorContext
    
    Returns true if EditorContext.setInModel(Object) can be called successfully.
    
    Specified by:
    
    canSetInModel in interface EditorContext<T>
  - checkAssignment
```
public abstract T checkAssignment(Object value)
```
    Description copied from interface: EditorContext
    
    Returns value cast to the type accepted by the Editor or throws a ClassCastException.
    
    Specified by:
    
    checkAssignment in interface EditorContext<T>
    
    Parameters:
    
    value - any value, including null
    
    Returns:
    
    value cast to the T type
  - doTraverseSyntheticCompositeEditor
```
public void doTraverseSyntheticCompositeEditor(EditorVisitor visitor)
```
  - getAbsolutePath
```
public String getAbsolutePath()
```
    Description copied from interface: EditorContext
    
    Returns the absolute path of the Editor within the hierarchy. This method should be preferred to calling getEditorDelegate().getPath() becasue not all LeafValueEditors are guaranteed to have an associated delegate.
    
    Specified by:
    
    getAbsolutePath in interface EditorContext<T>
  - getEditedType
```
public abstract Class<T> getEditedType()
```

    getEditedType in interface EditorContext<T>
  - getEditor
```
public Editor<T> getEditor()
```
    Description copied from interface: EditorContext
    
    Returns the associated Editor.

    getEditor in interface EditorContext<T>
  - getEditorDelegate
```
public EditorDelegate<T> getEditorDelegate()
```
    Description copied from interface: EditorContext
    
    Returns the EditorDelegate associated with the current Editor, which may be null for LeafValueEditors.
    
    Specified by:
    
    getEditorDelegate in interface EditorContext<T>
  - getFromModel
```
public abstract T getFromModel()
```
    Description copied from interface: EditorContext
    
    Returns the value to be edited by the current editor.
    
    Specified by:
    
    getFromModel in interface EditorContext<T>
  - halt
```
public void halt()
```
  - isHalted
```
public boolean isHalted()
```
  - setEditorDelegate
```
public void setEditorDelegate(AbstractEditorDelegate<T,?> delegate)
```
  - setInModel
```
public abstract void setInModel(T data)
```
    Description copied from interface: EditorContext
    
    Sets a new value in the data hierarchy being edited. The EditorContext.checkAssignment(Object) method may be used to avoid an unsafe generic cast.
    
    Specified by:
    
    setInModel in interface EditorContext<T>
  - traverse
```
public void traverse(EditorVisitor visitor,
                     AbstractEditorDelegate<?,?> next)
```
  - traverseSyntheticCompositeEditor
```
public void traverseSyntheticCompositeEditor(EditorVisitor visitor)
```
    Description copied from interface: EditorContext
    
    Traverse an editor created by CompositeEditor.createEditorForTraversal() that reflects an uninitialized instance of a composite sub-editor. This can be used to examine the internal structure of a CompositeEditor even if there are no data elements being edited by that editor.
