A LinuxInputDevice listens for events on a Linux input device node, typically one of the files in /dev/input. When events are waiting to be processed on the device it notifies its listener on a thread provided by its runnable processor object.

Event lines are accumulated in a buffer until an event "EV_SYN EV_SYN_REPORT 0" is received. At this point the listener is notified. The listener can then use the methods getEventType(), getEventCode() and getEventValue() to obtain the details of the current event line to process. nextEvent() and hasNextEvent() are used to iterate over pending events.

To save on RAM and GC, event lines are not objects.

public boolean is5Way()

Implements com.sun.glass.ui.monocle.InputDevice.is5Way.

Returns:boolean

Doc from com.sun.glass.ui.monocle.InputDevice.is5Way.

true if the device provides direction arrow keys (UP, DOWN, LEFT and RIGHT) and a selection key.

Returns:boolean

Doc from com.sun.glass.ui.monocle.InputDevice.isFullKeyboard.

true if the device provides keys for the letters 'A' through 'Z', the digits '0' through '9' and also SPACE, SHIFT and TAB keys in addition to directional arrows and a selection key.

public boolean isMultiTouch()

Implements com.sun.glass.ui.monocle.InputDevice.isMultiTouch.

Returns:boolean

true if the device provides touch input for more than one touch point.

Annotations
@Override
isQuietback to summary
pack-priv boolean isQuiet()

Asks whether the device is quiet. "Quiet" means that the event reader is blocked waiting for events, the buffer is empty and the event processor is not scheduled. Called on the application thread.

isRelativeback to summary
public boolean isRelative()

Implements com.sun.glass.ui.monocle.InputDevice.isRelative.

Returns:boolean

Doc from com.sun.glass.ui.monocle.InputDevice.isRelative.

true if the device provides relative pointing events. Relative pointing events are those received from devices where the event signifies a relative change in cursor position on the screen. For example, a mouse, trackball, trackpad or joystick is a relative pointing device. A touch screen is an sbsolute pointing device.
