Class AbstractAccessSensorService

java.lang.Object

com.twl.xg.service.AbstractAccessSensorService

Direct Known Subclasses:

AccessSensorService, MockAccessSensorService

public abstract class AbstractAccessSensorService
extends java.lang.Object

This abstract class defines the basic operations to communicate with sensors. Also provides some common methods for storing sensor or data into database. To use this class, one need to extend this abstract class first, and implement getDataFromSensor() method.

Method Detail

getDataFromSensor

public abstract SensorDataEntity getDataFromSensor(java.lang.String sensorIp)
                                            throws com.fasterxml.jackson.core.JsonProcessingException

For the input sensor IP, get current data from the sensor, map the data to a SensorDataEntity object. For the data types, use the global dataTypeList bean to decide what kind of data to fetch.

Parameters:

sensorIp - The IPv6 address of the sensor you want to fetch from.

Returns:

A SensorDataEntity object contains the data.

Throws:

com.fasterxml.jackson.core.JsonProcessingException

getAllCurrentSensorData

@Transactional
public DataPackage getAllCurrentSensorData()
                                    throws com.fasterxml.jackson.core.JsonProcessingException

Fetch data from each sensor, map the data to well formatted Java Object. If there is no sensor in database, return null.

Returns:

A list of BorderRouterWrapper

Throws:

com.fasterxml.jackson.core.JsonProcessingException

saveDataFromSensor

@Transactional
public SensorDataEntity saveDataFromSensor(java.lang.String sensorIp)
                                    throws com.fasterxml.jackson.core.JsonProcessingException

Fetch current data from the input sensor IP, store the data into database.

Parameters:

sensorIp - The IPv6 address of the sensor you want to fetch from.

Returns:

A SensorDataEntity object contains the data.

Throws:

com.fasterxml.jackson.core.JsonProcessingException

getDataFromSensorForBorderRouter

@Transactional
public BorderRouterWrapper getDataFromSensorForBorderRouter(BorderRouterEntity borderRouter)
                                                     throws com.fasterxml.jackson.core.JsonProcessingException

Get current data from sensors connected to the input border router.

Parameters:

borderRouter - The instance of border router you want to fetch data from.

Returns:

An instance of BorderRouterWrapper that contains data.

Throws:

java.lang.NullPointerException - if the input borderRouter entity is null.

com.fasterxml.jackson.core.JsonProcessingException

saveAllCurrentDataFromSensor

@Transactional
public boolean saveAllCurrentDataFromSensor()
                                     throws com.fasterxml.jackson.core.JsonProcessingException

Fetch and save the current data set of each sensor in database.

Returns:

true if there are sensors in database, return false if there is no sensor in database.

Throws:

com.fasterxml.jackson.core.JsonProcessingException - the json processing exception
