Scol

h1. Creation of a new type for Scol

Similarly to the functions, it is possible to extend Scol language by creating new data types using the integration of a new C/C++ plugin.

h2. Definition of "Bloc" type

We will create a new Scol type, which will store a name and an integer value. We will also have to define the getters and setters for both properties. As we will implement this new type using a C++ class, we'll also define default constructor and destructor.

Let's create a new C++ header file named *Bloc.h*. Copy/paste the following code into it :

<pre>

 // Include providing MAX_PATH define

 #include <windows.h>

 /*!

  * Bloc class. A simple class that has a name and a value associated with it.

  * It allows simple operations like getting and setting its attributes.

  *

  **/

 class Bloc

 {

 private:

    int value;	            //!< The value of the bloc

    char name[MAX_PATH];    //!< The name of the bloc

 public:

    int getValue();

    char* getName();

    void setName(char*);

    void setValue(int);

    Bloc(void);

    ~Bloc(void);

 };

</pre>

Now, let's create the source file (*Bloc.cpp*) in which we will define all the functions. There is nothing specific to explain about this source code, it's pretty easy to understand it.

<pre>

 #include "Bloc.h"

 #include <string.h>

 #include <stdio.h>

 /*!

 * \brief Bloc constructor

 * 

 */

 Bloc::Bloc(void)

 {

    value=0;

    strcpy_s(name,"SuperBloc");

 }

 /*!

 * \brief Bloc destructor

 * 

 */

 Bloc::~Bloc(void)

 {

 }

 /*!

 * \brief Gives the bloc value

 * \return The bloc value 

 */

 int Bloc::getValue()

 {

    return value;

 }

 /*!

 * \brief Gives the bloc name

 * \return The bloc name

 * 

 */

 char * Bloc::getName()

 {

    return name;

 }

 /*!

 * \brief Set the bloc value

 * \param myValue : The new value 

 */

 void Bloc::setValue(int myValue)

 {

    value = myValue;

 }

 /*!

 * \brief Set the bloc name

 * \param myValue : The new name 

 */

 void Bloc::setName(char* myName)

 {

    strncpy_s(name, myName, MAX_PATH-1);

 }

</pre>
