OptionalAlignmentTernaryFunction
class OptionalAlignmentTernaryFunction<A, OA : ObservableValue<A>, B, OB : ObservableValue<B>, C, OC : ObservableValue<C>>(argA: OA, argB: OB, argC: OC, lambda: (A, B, C) -> Alignment?) : TernaryFunction<Alignment?, A, OA, B, OB, C, OC> , ObservableOptionalAlignment
Boilerplate which avoids having to use generics.
Similar to AlignmentTernaryFunction, but the value can also be null.
