const list: ITreeNode<number>[] = [];
const model = new ObjectTreeModel<number>(toSpliceable(list));
model.setChildren(null, Iterator.fromArray([
{ element: 0 },
{ element: 1 },
{ element: 2 }
]));
assert.deepEqual(toArray(list), [0, 1, 2]);
assert.equal(model.size, 3);
model.setChildren(null, Iterator.fromArray([
{ element: 3 },
{ element: 4 },
{ element: 5 },
]));
assert.deepEqual(toArray(list), [3, 4, 5]);
assert.equal(model.size, 3);
model.setChildren(null, Iterator.empty());
assert.deepEqual(toArray(list), []);

});示例2: test
test('sorter', () => {
let compare: (a: string, b: string) => number = (a, b) => a < b ? -1 : 1;
const list: ITreeNode<string>[] = [];
const model = new ObjectTreeModel<string>(toSpliceable(list), { sorter: { compare(a, b) { return compare(a, b); } } });
