NotNilValue

Overview

Not Nil is an operator used in the Oxygene language. The expression on the left side is evaluated first, if it's nil, the right side won't be evaluated but instead returns nil right away. The result type is always the most common type that matches; when using this operator for methods with a valuetype result, the result is a nillable type.
