Method Detail

deleteSensor

public static void deleteSensor()

Delete all sensors (by simply setting the first sensor reference to null}

insertSensor

public static void insertSensor(String Symbol,
                String Unit,
                String Description,
                String Explanation,
                String type,
                int scaler,
                int min,
                int max,
                boolean hasHistory,
                int poll,
                Handler handler)

Inserts new sensor in list, calling appropriate Sensor instance

Parameters:

Symbol - String of the sensor symbol (used for retrieving sensors)

Unit - String of the sensor unit (used in titles of visualisations)

Description - String of the sensor description (used in titles of visualisations)

type - String with the type of the sensor (used in the recording thread to handle data differently)

scaler - Scaler of the values as an exponent of 10

min - Minimum value of the sensor, if supported, expressed with the scaler in mind

max - Maximum value of the sensor, if supported, expressed with the scaler in mind

hasHistory - Flag if Handler implementing the sensor supports history for it

poll - Polling time in millisecond - if zero, the handler will block properly when called frequently, e.g., realising the recording through a callback

handler - Reference to the Handler implementing the sensor

setSensorStatus

public static void setSensorStatus(String Symbol,
                   int status,
                   String reason,
                   Runnable thread)

Finds sensor based on Symbol and sets valid flag

Parameters:

Symbol - String to sensor symbol trying to find

status - Status of sensor after being found

reason - Status string of sensor after being found

thread - Reference to Runnable of the acquisition thread being used right now

getSensorStatus

public static int getSensorStatus(String Symbol)

Finds sensor based on Symbol and returns its current status

Parameters:

Symbol - String of the sensor symbol to be found

Returns:

status of the sensor, SENSOR_INVALID if nothing is found

findHandler

public static Handler findHandler(String Symbol)

Finds sensor based on Symbol and returns handler serving sensor

Parameters:

Symbol - String of the sensor symbol to be found

Returns:

Reference to the Handler that implements the sensor symbol

findSensor

public static Sensor findSensor(String Symbol)

Finds sensor based on Symbol and returns reference to the Sensor

Parameters:

Symbol - String of the sensor symbol to be found

Returns:

Reference to the Sensor of this symbol

findScaler

public static int findScaler(String Symbol)

Finds sensor based on Symbol and returns its scaler

Parameters:

Symbol - String of the sensor symbol to be found

Returns:

Scaler of the sensor being found
