OptionalVAlignmentBinaryFunction
class OptionalVAlignmentBinaryFunction<A, OA : ObservableValue<A>, B, OB : ObservableValue<B>>(argA: OA, argB: OB, lambda: (A, B) -> VAlignment?) : BinaryFunction<VAlignment?, A, OA, B, OB> , ObservableOptionalVAlignment
Boilerplate which avoids having to use generics.
Similar to VAlignmentBinaryFunction, but the value can also be null.
