Syntax

template<typename FuncType, typename FirstTupleType, typename... TupleTypes>
FORCEINLINEvoid VisitTupleElements
(
    FuncType && Func,
    FirstTupleType && FirstTuple,
    TupleTypes &&... Tuples
)

Remarks

Visits each element in the specified tuples in parallel and applies them as arguments to the functor. All specified tuples must have the same number of elements.

Example:

void Func(const TTuple& Tuple1, const TTuple& Tuple2) { // Equivalent to: // Functor(Tuple1.Get<0>(), Tuple2.Get<0>()); // Functor(Tuple1.Get<1>(), Tuple2.Get<1>()); // Functor(Tuple1.Get<2>(), Tuple2.Get<2>()); VisitTupleElements(Functor, Tuple1, Tuple2); }

Parameters

Parameter	Description
Func	The functor to apply.
Tuples	The tuples whose elements are to be applied to the functor.
