getName

public String getName()

Returns the name.

Returns:

String; name

addStream

public <T extends Number> DataStream<T> addStream(Quantity<T,?> quantity,
                                                  T thetaCong,
                                                  T thetaFree)

Add a non-speed stream for the quantity to this data source.

Type Parameters:

T - implicit data type

Parameters:

quantity - Quantity<T, ?>; quantity

thetaCong - T; standard deviation of this quantity of measurements in congestion by this data source

thetaFree - T; standard deviation of this quantity of measurements in free flow by this data source

Returns:

DataStream; the created data stream

Throws:

IllegalArgumentException - if the quantity is speed

addStreamSI

public <T extends Number> DataStream<T> addStreamSI(Quantity<T,?> quantity,
                                                    double thetaCong,
                                                    double thetaFree)

Add a stream for the quantity to this data source.

Type Parameters:

T - implicit data type

Parameters:

quantity - Quantity<T, ?>; quantity

thetaCong - double; standard deviation of this quantity of measurements in congestion by this data source in SI
