void SetNext(Ptr< PhasedArraySpectrumPropagationLossModel > next)
Used to chain various instances of PhasedArraySpectrumPropagationLossModel.
virtual Ptr< SpectrumSignalParameters > DoCalcRxPowerSpectralDensity(Ptr< const SpectrumSignalParameters > params, Ptr< const MobilityModel > a, Ptr< const MobilityModel > b, Ptr< const PhasedArrayModel > aPhasedArrayModel, Ptr< const PhasedArrayModel > bPhasedArrayModel) const =0
virtual int64_t DoAssignStreams(int64_t stream)=0
Assign a fixed random variable stream number to the random variables used by this model.
int64_t AssignStreams(int64_t stream)
If this loss model uses objects of type RandomVariableStream, set the stream numbers to the integers ...
Ptr< PhasedArraySpectrumPropagationLossModel > GetNext() const
Return the pointer to the next PhasedArraySpectrumPropagationLossModel, if any.
