Package com.pi4j.wiringpi

Class GpioInterruptEvent

java.lang.Object

java.util.EventObject

com.pi4j.wiringpi.GpioInterruptEvent

All Implemented Interfaces:

Serializable

public class GpioInterruptEvent
extends EventObject

This class provides the event object for GPIO interrupt state changes. Before using the Pi4J library, you need to ensure that the Java VM in configured with access to the following system libraries:

• pi4j
• wiringPi

This library depends on the wiringPi native system library. (developed by Gordon Henderson @ http://wiringpi.com/)
