Solution: Interpreter Combined With Adapter (And A Proxy)¶

/trainings/material/soup/cxx-code/design-patterns-interpreter/expressions/expression-sensorvalue.h¶

#pragma once

#include "expression.h"
#include "sensor.h"


class SensorValueExpression : public Expression
{
public:
    SensorValueExpression(Sensor* sensor) : _sensor(sensor) {}

    int evaluate() override;

private:
    Sensor* _sensor;
};

/trainings/material/soup/cxx-code/design-patterns-interpreter/expressions/expression-sensorvalue.cpp¶

#include "expression-sensorvalue.h"


int SensorValueExpression::evaluate()
{
    return _sensor->get_temperature();
}
