For large tree data sets you probably want to only load the necessary data for the visible nodes of the tree. When a user expands a node, it starts to load the children of that node.
对于较大的树型数据集，您可能只想加载可见树节点的必要数据，当用户展开一个节点后再记载该节点的子节点。
When a user clicks on one of the nodes in the example, the tree will ask the store to load the item and the store will request the resource.
在本例中，当用户点击其中一个节点时，树将请求存储库加载条目，存储库将请求资源。
