Sensor Listner is one of Infairy broadcast channel which can let all developer receive the evetn from all other bundle in Infairy.
Developer can listen Sensor broadcast channel to get all event by implement "EventSensorDNA" class, please follow the step as below:
First, import package as follows:
Developer can listen Sensor broadcast channel to get all event by implement "EventSensorDNA" class, please follow the step as below:
import org.osgi.service.event.Event;
import org.osgi.service.event.EventHandler;
import com.infairy.cocina.SDK.gene.EventSensorDNA;
then, implement "EventHandler" in your bundle class:
package yourBundle;
public class CommData implements BundleActivator, EventHandler{
....
}
Third, implement HandleEvent() method,
public void handleEvent(Event evnt) {
...
}
Last, do not forget listen Sensor broadcast channel in start() method,
package yourBundle;
public class CommData implements BundleActivator, EventHandler{
....
public void start(BundleContext context) throws Exception {
...
device.ListenBroadcast(context, this, device.BROADCAST_CHANNEL_SENSOR);
}
}
after done the process as above, you can get the event from all other sensor:
public void handleEvent(Event evnt) {
if(evnt==null) return;
//Cast the event by EventSensorDNA from the property of BROADCAST_SENSOR_TRIGGER_EVENTOBJECT
EventSensorDNA ESO=(EventSensorDNA)evnt.getProperty(device.BROADCAST_SENSOR_TRIGGER_EVENTOBJECT);
if(ESO!=null){
if(ESO.TYPE.equals("")) return;
String TYPE=ESO.TYPE;
if(TYPE.equals("")) return;
String triggerZID=ESO.ZID; //Get the trigger device id
if(triggerZID.equals(""))
return;
//Analysis by trigger type, The trigger type defined by com.infairy.cocina.SDK.device.DevicePool#TROGGET_TYPE_xxx
if(TYPE.equals(device.TRIGGER_TYPE_TRIGGER)){
...
}
}
}
Now, you learned how to get the sensor event.Next, we will show you how to send the sensor event:
//Create EventSensorDNA object
EventSensorDNA ev=new EventSensorDNA();
//Assign the device id
ev.ZID=myBundleID;
//Set the trigger channel
ev.CHANNEL=0;
//Assigned trigger type
ev.TYPE=device.TRIGGER_TYPE_TRIGGER;
//Alias
ev.ALIAS="MyWeather";
//Value defined
ev.NOW_VALUE="28";
ev.PREVIOUS_VALUE="27";
ev.NOW_UNIT=device.DEVICE_VALUE_UNIT_DEGREE_C;
ev.PREVIOUS_UNIT=device.DEVICE_VALUE_UNIT_DEGREE_C;
//Broadcast the event
device.SensorBroadcast(ev);
ev=null;
The EventSensorDNA interface shows as below:

public String ZID="";
