## Description

Used to overload the `Not</api/language/operators/bitwise_logical/not>` operator, providing custom functionality.

## Notes

Create an <span class="title-ref">Operator_Not</span> function in a class to specify the functionality of the `Not</api/language/operators/bitwise_logical/not>` operator for that class. Whenever you use the `Not</api/language/operators/bitwise_logical/not>` operator in your code to operate on two instances of the class, your <span class="title-ref">Operator_Not</span> function will be called.

In the function, the `Self</api/language/self_keyword>` instance is the only operand. No parameters are passed.

## Sample code

Suppose you define a class MyResult with the property a as `Boolean</api/data_types/boolean>`. <span class="title-ref">Operator_Not</span> is defined on the class as:

``` xojo
Function Operator_Not As Boolean
  Return Not Self.a
End Function
```
