xyz.cp74.evdev.InputDevice

All Implemented Interfaces:

InputDevicePath

public class InputDevice
extends Object
implements InputDevicePath

InputDevice InputDevice read events from input devices provided by the event device (evdev) interface of the linux kernel. The character devices in the directory /dev/input/eventX are read and decoded. You can attach a listener to an event with given type and code.

onEvent

public void onEvent(EventListener listener)

Sets a global listener that listen to all events. It's only possible to set one global listener.

Parameters:

listener - instance of EventListener that should receive events

onEvent

public void onEvent(EventType type,
                    int code,
                    EventListener listener)

Sets an event listener for given event type and code. It's only possible to set one RawListener for one tuple of type and code.

Parameters:

type - the EventType to listen for

code - the code of the event

listener - instance of EventLister that should receive events

onEvent

public void onEvent(EventType type,
                    int code,
                    Predicate<Integer> predicate,
                    EventListener listener)

Sets an event listener for given event type and code. It's only possible to set one RawListener for one tuple of type and code.

Parameters:

type - the EventType to listen for

code - the code of the event

predicate - predicate to fulfil

listener - instance of EventLister that should receive events

onKey

public void onKey(int code,
                  EventListener listener)

Sets an event listener for an key event and code. It's only possible to set one RawListener for one tuple of type and code.

Parameters:

code - the code of the event

listener - instance of EventLister that should receive events

onKey

public void onKey(int code,
                  Predicate<Integer> predicate,
                  EventListener listener)

listener - instance of EventLister that should receive events

onAxis

public void onAxis(int code,
                   EventListener listener)

Sets an event listener for an axis event and code. It's only possible to set one RawListener for one tuple of type and code.

Parameters:

code - the code of the event

listener - instance of EventLister that should receive events

onAxis

public void onAxis(int code,
                   Predicate<Integer> predicate,
                   EventListener listener)
