Operator_Add Method

Used to overload the + operator, providing custom functionality.

Syntax


Notes

Create an Operator_Add function in a class to specify the functionality of the + operator for that class.

In the function, the Self instance is one of the operands and the other operand is passed as a parameter. Operator_Add assumes the Self instance is on the left and the passed instance is on the right.


Example

Suppose you have a class, Vector, that can store a vector of modest size. To define the + operator for this class, create a method of the Vector class called Operator_Add.

The Vector class has two Integer properties, x and y.

Operator_Add is defined as:

Function Operator_Add (rhs as Vector) as Vector
 //rhs stands for right-hand-side, the vector to be added to Self
  Dim ret as New Vector   the sum of the two vectors
 ret.x= Self.x + rhs.x
 ret.y= Self.y + rhs.y

Return ret
