示例1:
/**
* Convert an IIterator into a list.
*/
function iteratorToList<T>(i: IIterator<T>): T[] {
const a: T[] = [];
for (let v = i.next(); v !== undefined; v = i.next()) {
a.push(v);
}
return a;
}
示例2: reduce
static _intersection<T>(iter: IIterator<Array<T>>): Set<T> | void {
// pop the first element of iter
let first = iter.next();
// first will be undefined if iter is empty
if (!first) {
return;
}
// "initialize" the intersection from first
let isect = new Set(first);
// reduce over the remaining elements of iter
return reduce(
iter,
(isect, subarr) => {
// filter out all elements not present in both isect and subarr,
// accumulate result in new set
return new Set(subarr.filter(x => isect.has(x)));
},
isect
);
}
