getReceiverExpression¶

Returns the receiver this name is applied to, considering qualified expressions, binary/unary operators, and qualified user types, or null if this name has no receiver.

For example, the receiver of b in a.b is a, the receiver of the + operator in a + b is a, the receiver of the ++ operator in a++ is a, and the receiver of B in the user type A.B is A. A bare, unqualified name has no receiver, so the result is null.
