  org.universAAL.lddi.samples.activityhub.client.MyActivityHubServiceConsumer

public class MyActivityHubServiceConsumer
extends Object

This class provides ontological service requests and processes the service responses This class is stateless; no objects (sensors) are stored here LogUtil from uAAL-Middleware is used here

Method Summary

void	deleteGui() close the GUI window, e.g. if the bundle is stopped; called by Activator
static List	getActivityHubSensorInfo(ActivityHubSensor ahs) Get details for a specific ActivityHub sensor Get the ontological service request Send service request to service bus Process the response Log errors if the call was not successful
static ServiceRequest	getAllActivityHubSensorsRequest() Create ontological service request no input output: resources that are controled by ActivityHub service
static ArrayList	getControlledActivityHubSensors() Get a list of all available ActivityHub sensors in the system Get the ontological service request Send service request to service bus Process the response Log errors if the call was not successful
void	getDeviceInfo(String sensorURI, int deviceType) The parameters are just URI-Strings to keep this class stateless A new ActivityHubSensor is created from the Ontology according to the URIs from the client application (client doesn't store Ontology Resource objects) Pass this sensor object in service request Process result list from service response Send result text array to GUI
void	getSensors() Fetch sensors from service bus and send to gui Process result list of ActivityHubSensors from service response Send just URI-Strings to client application to decouple from Ontology-stuff Display sensor list in GUI

Constructor Detail

MyActivityHubServiceConsumer

public MyActivityHubServiceConsumer(ModuleContext mc,
                                    ActivityHubClient ahc)

Contructor

Parameters:

mc - uAAL-Middleware ModuleContext

ahc - link to client application

Method Detail

getControlledActivityHubSensors

public static ArrayList getControlledActivityHubSensors()

Get a list of all available ActivityHub sensors in the system Get the ontological service request Send service request to service bus Process the response Log errors if the call was not successful

Returns:

ArrayList with ActivityHubSensors (Ontology Resource objects)

getActivityHubSensorInfo

public static List getActivityHubSensorInfo(ActivityHubSensor ahs)

Get details for a specific ActivityHub sensor Get the ontological service request Send service request to service bus Process the response Log errors if the call was not successful

Returns:

List with ? (Ontology Resource objects)

getSensors

public void getSensors()

Fetch sensors from service bus and send to gui Process result list of ActivityHubSensors from service response Send just URI-Strings to client application to decouple from Ontology-stuff Display sensor list in GUI

getDeviceInfo

public void getDeviceInfo(String sensorURI,
                          int deviceType)

The parameters are just URI-Strings to keep this class stateless A new ActivityHubSensor is created from the Ontology according to the URIs from the client application (client doesn't store Ontology Resource objects) Pass this sensor object in service request Process result list from service response Send result text array to GUI

Parameters:

sensorURI - is the resourceURI

deviceType - is the type-id for the ActivityHubSensor

getAllActivityHubSensorsRequest

public static ServiceRequest getAllActivityHubSensorsRequest()

Create ontological service request no input output: resources that are controled by ActivityHub service

deleteGui

public void deleteGui()

close the GUI window, e.g. if the bundle is stopped; called by Activator
