createSelector2<S, R1, R2, T> function
Create a memoized selector by combining two selectors. It will cache the
result of the combiner
function, and only recompute when the provided
selectors deliver new results.
A complete example can be seen as part of the Selector documentation.
Implementation
Selector<S, T> createSelector2<S, R1, R2, T>(
Selector<S, R1> selector1,
Selector<S, R2> selector2,
T Function(R1, R2) combiner, {
T Function(R1, R2) Function(T Function(R1, R2))? memoize,
}) {
final memoized = (memoize ?? memo2)(combiner);
return (S state) {
return memoized(selector1(state), selector2(state));
};
}
