- Constructor Detail
  - PathManipulator
```
public PathManipulator()
```
    Construct a new manipulator that uses rectangular grab-handles.
  - PathManipulator
```
public PathManipulator(GrabHandleFactory f)
```
    Construct a new manipulator using the given grab-handle factory.
- Method Detail
  - newInstance
```
public FigureDecorator newInstance(Figure f)
```
    Create a new instance of this manipulator. The new instance will have the same grab handle, and interactor for grab-handles, as this one.
    
    Specified by:
    
    newInstance in class FigureDecorator
    
    Parameters:
    
    f - The figure
    
    Returns:
    
    The new instance of the figure decorator.
  - refresh
```
public void refresh()
```
    Refresh the geometry.
    
    Specified by:
    
    refresh in class Manipulator
  - setChild
```
public void setChild(Figure f)
```
    Set the child figure. If we have any grab-handles, lose them. Then get a path geometry object set on this figure (the manipulator, not the child) and create grab-handles on it.
    
    Overrides:
    
    setChild in class FigureDecorator
    
    Parameters:
    
    f - The child figure.
