 `Tree` has the following method, which returns the currently selected array of nodes.
 | Method | Description | Parameters |
 | --------------- | ---------------------------------------- | ---------------------------------------- |
-| filter | filter all tree nodes, filtered nodes will be hidden | (query: string) |
-| getCheckedNodes | If the node can be selected (`show-checkbox` is `true`), it returns the currently selected array of nodes | (leafOnly: boolean) |
-| getCheckedKeys | If the node can be selected (`show-checkbox` is `true`), it returns the currently selected array of node's keys | (leafOnly: boolean) |
-| setCheckedKeys | set certain nodes to be checked | (keys: TreeKey[]) |
-| setChecked | set node to be checked or not | (key: TreeKey, checked: boolean) |
