# array template object

Path: /sdk/add_on/scriptarray/

The `array` type is a template object that allow the scripts to declare arrays of any type. Since it is a generic class it is not the most performatic due to the need to determine characteristics at runtime. For that reason it is recommended that the application registers a template specialization for the array types that are most commonly used.

The type is registered with `RegisterScriptArray(asIScriptEngine*)`.

## Public C++ interface

    class CScriptArray
    {
    public:
      // Constructor
      CScriptArray(asUINT length, asIObjectType *ot);
      virtual ~CScriptArray();

      // Memory management
      void AddRef();
      void Release();

      // Type information
      asIObjectType *GetArrayObjectType() const;
      int            GetArrayTypeId() const;
      int            GetElementTypeId() const;

      // Get the current size
      asUINT GetSize();

      // Resize the array
      void   Resize(asUINT numElements);

      // Get a pointer to an element. Returns 0 if out of bounds
      void  *At(asUINT index);

      // Copy the contents of one array to another (only if the types are the same)
      CScriptArray &operator=(const CScriptArray&);
    };

## Public script interface

      class array<class T>
      {
        array();
        array(uint length);

        // Access elements
        // T & operator [] (uint)
        // const T & operator [] (uint) const

        array<T> opAssign(const array<T> & in);

        uint length();
        void resize(uint);
      }

## Script example

      int main()
      {
        array<int> arr(3);
        arr[0] = 1;
        arr[1] = 2;
        arr[2] = 3;

        int sum = 0;
        for( uint n = 0; n < arr.length(); n++ )
          sum += arr[n];

        return sum;
      }
