removeObserver

Remove observer from scenario simulation

Since R2022a

Syntax

removeObserver(ScenarioSim,ObserverName)

Description

removeObserver(ScenarioSim,ObserverName) removes the observer named ObserverName from the Simulink.ScenarioSimulation object ScenarioSim.

Examples

Remove Observer from Scenario Simulation

Create ScenarioSim, a Simulink.ScenarioSimulation object.

rrApp = roadrunner('C:\RoadRunnerProject');
openScenario(rrApp,'TrajectoryCutIn');
ScenarioSim = createSimulation(rrApp);

Create the class mySysObserver, which inherits from matlab.System base class. The mySysObserver class represents an observer.

classdef mysysObserver < matlab.System

properties(Access=private)
% …
end
methods
% constructor for the System object
function obj = mysysObserver()
end
end


methods(Access = protected)

%reset the values
function resetImpl(obj)
obj.mScenarioSimObj = Simulink.ScenarioSimulation.find('ScenarioSimulation', 'SystemObject', obj);
obj.mScenarioSimActorList = [];
obj.mIsPacingTurnedOff = false;
end



% get the required parameter values
function stepImpl(obj)
mSimulationPace = obj.mScenarioSimObj.get('SimulationPace');
mScenarioSimActorList = obj.mScenarioSimObj.get('ActorSimulation');
end
end
end

Add the observer to the scenario.

obsStatus = addObserver(ScenarioSim,'ReadPaceandActors',mysysObserver);

Remove the observer from the scenario.

removeObserver(ScenarioSim,'ReadPaceandActors');

Input Arguments
