Constructor Detail

AbstractController

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
