protected AbstractController(java.lang.String name,
                             Component[] components,
                             Controller[] children,
                             Rumbler[] rumblers)
```
    Protected constructor for a controller containing the specified axes, child controllers, and rumblers
    
    Parameters:
    
    name - name for the controller
    
    components - components for the controller
    
    children - child controllers for the controller
    
    rumblers - rumblers for the controller
- Method Detail
  - getControllers
```
public final Controller[] getControllers()
```
    Returns the controllers connected to make up this controller, or an empty array if this controller contains no child controllers. The objects in the array are returned in order of assignment priority (primary stick, secondary buttons, etc.).
    
    Specified by:
    
    getControllers in interface Controller
  - getComponents
```
public final Component[] getComponents()
```
    Returns the components on this controller, in order of assignment priority. For example, the button controller on a mouse returns an array containing the primary or leftmost mouse button, followed by the secondary or rightmost mouse button (if present), followed by the middle mouse button (if present). The array returned is an empty array if this controller contains no components (such as a logical grouping of child controllers).
    
    Specified by:
    
    getComponents in interface Controller
  - getComponent
```
public final Component getComponent(Component.Identifier id)
```
    Returns a single component based on its identifier, or null if no component with the specified type could be found.
    
    Specified by:
    
    getComponent in interface Controller
  - getRumblers
```
public final Rumbler[] getRumblers()
```
    Returns the rumblers for sending feedback to this controller, or an empty array if there are no rumblers on this controller.
    
    Specified by:
    
    getRumblers in interface Controller
  - getPortType
```
public Controller.PortType getPortType()
```
    Returns the port type for this Controller.
    
    Specified by:
    
    getPortType in interface Controller
    
    Returns:
    
    PortType.UNKNOWN by default, can be overridden
  - getPortNumber
```
public int getPortNumber()
```
    Returns the zero-based port number for this Controller.
    
    Specified by:
    
    getPortNumber in interface Controller
    
    Returns:
    
    0 by default, can be overridden
  - getName
```
public final java.lang.String getName()
```
    Returns a human-readable name for this Controller.
    
    Specified by:
    
    getName in interface Controller
  - toString
```
public java.lang.String toString()
```
    Returns a non-localized string description of this controller.
    
    Overrides:
    
    toString in class java.lang.Object
  - getType
```
public Controller.Type getType()
```
    Returns the type of the Controller.
    
    Specified by:
    
    getType in interface Controller
  - setEventQueueSize
```
public final void setEventQueueSize(int size)
```
    Creates a new EventQueue. Events in old queue are lost.
    
    Specified by:
    
    setEventQueueSize in interface Controller
  - setDeviceEventQueueSize
```
protected void setDeviceEventQueueSize(int size)
                                throws java.io.IOException
```
    Plugins override this method to adjust their internal event queue size
    
    Throws:
    
    java.io.IOException
  - getEventQueue
```
public final EventQueue getEventQueue()
```
    Description copied from interface: Controller
    
    Get the device event queue
    
    Specified by:
    
    getEventQueue in interface Controller
  - getNextDeviceEvent
```
protected abstract boolean getNextDeviceEvent(Event event)
                                       throws java.io.IOException
```
    Throws:
    
    java.io.IOException
  - pollDevice
```
protected void pollDevice()
                   throws java.io.IOException
```
    Throws:
    
    java.io.IOException
  - poll
```
public boolean poll()
```
    Description copied from interface: Controller
    
    Polls axes for data. Returns false if the controller is no longer valid. Polling reflects the current state of the device when polled.
    
    Specified by:
    
    poll in interface Controller
