函数 objsIterator

示例

var objs = [{x: 1}, {x: 2}];
var objsItr = objsIterator<number>(objs, ['x']);

// example1
for (let d of objsItr) {
    console.log(d);
}

// example2
var m = min(objsItr);

// example3
const externalData = [{x:1}, {x:1}, {x:1}, {x:1}, {x:1}, {x:1}, {x:1}, {x:1}, {x:1}];
const externalIterator = objsIterator(externalData, ['x']);
for (let e of externalIterator) { console.log(e) };

// example4
const externalData2 = [{ c: {x:1, y:2, z: 3} }, { c: {x: 4, y: 5, z: 6} }, { c: {x: 7, y: 8, z: 9} }];
function* g() {
    const oi = objsIterator(externalData2, ['c']);
    for (let e of oi) {
        yield e.x;
        yield e.y;
        yield e.z;
    }
}
const externalIterator2 = g();
for (let e of externalIterator) { console.log(e) };
