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