- Method Detail
  - getFeatureID
```
java.lang.String getFeatureID()
```
  - isOn
```
boolean isOn()
```
  - isTwoState
```
boolean isTwoState()
```
    Indicates whether the feature can be either on or off, without any other states. This is used by the tool bar and menu-bar menus to determine whether the feature's enable/disable button or menu item should be displayed with an indicator that it's either on or off. In the case of a menu the indicator is a check box. In the case of a tool bar button the indicator is a dot above the button.
    
    Returns:
    
    true if the feature has only two states, otherwise off.
  - turnOn
```
void turnOn(boolean tf)
```
  - getName
```
java.lang.String getName()
```
