- - Custom Classes? (http://www.chiefdelphi.com/forums/showthread.php?t=109471)

How would I go about creating a custom class? For example, I want a class that has a digitalInput encapsulated within it. In simple terms, How would I convert my existing LimitSwitch class (https://github.com/itguy51/FRC4014-2...mitSwitch.java) into C++? I have never actually used C++ in Object-Oriented programming other than simple things like in Visual Studio for demonstrations. I guessed how, and got this:

Code:

class limitSwitch

{

        DigitalInput di;

        limitSwitch::limitSwitch(UINT32 port){

                di(port);

        }

        bool limitSwitch::getState(){

                return di.Get() == 1;

        }

};

which is FULL of errors, there are more lines in the error log than there are in the cpp file. I get "Error: Expected ')' before "port"" and am confused because that makes no sense. I want to pass an argument to the constructor so that it assigns the DigitalInput to the initialized port.
getState is supposed to return true/false based on the state of the switch.

Re: Custom Classes?

Two ways of doing it. One is totally inline as you're doing it (which isn't really the C++ way of doing it).

Code:

#include <wpilib.h>



class LimitSwitch

{

public:



    LimitSwitch(UINT32 port) :

        di(port)

    {}

    

    bool getState()

    {

        return di.Get() != 0;

    }



private:

    DigitalInput di;

};

Or split into cpp/h files. Here's LimitSwitch.h:

Code:

#ifndef __LIMITSWITCH_H

#define __LIMITSWITCH_H



class LimitSwitch

{

public:



    LimitSwitch(UINT32 port); 

    

    bool getState();



private:

    DigitalInput di;

};

#endif

And LimitSwitch.cpp:

Code:

#include <wpilib.h>

#include "LimitSwitch.h"



LimitSwitch::LimitSwitch(UINT32 port) :

    di(port)

{}



bool LimitSwitch::getState()

{

    return di.Get() != 0;

}
