### Method
`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 | Accept a parameter which will be used as first parameter for filter-node-method |
| getCheckedNodes | If the node can be selected (`show-checkbox` is `true`), it returns the currently selected array of nodes | Accept a boolean type parameter whose default value is `false`. If the parameter is `true`, it only returns the currently selected array of sub-nodes.|
| getCheckedNodes | If the node can be selected (`show-checkbox` is `true`), it returns the currently selected array of nodes | Accept a boolean type parameter whose default value is `false`. If the parameter is `true`, it only returns the currently selected array of sub-nodes. |
| setCheckedNodes | set certain nodes to be checked, only works when `node-key` is assigned | an array of nodes to be checked |
| getCheckedKeys | If the node can be selected (`show-checkbox` is `true`), it returns the currently selected array of node's keys | (leafOnly) Accept a boolean type parameter whose default value is `true`. If the parameter is `true`, it only returns the currently selected array of sub-nodes.|
| getCheckedKeys | If the node can be selected (`show-checkbox` is `true`), it returns the currently selected array of node's keys | (leafOnly) Accept a boolean type parameter whose default value is `true`. If the parameter is `true`, it only returns the currently selected array of sub-nodes. |
| setCheckedKeys | set certain nodes to be checked, only works when `node-key` is assigned | (keys, leafOnly) Accept two parameters: 1. an array of node's keys to be checked 2. a boolean type parameter whose default value is `true`. If the parameter is `true`, it only returns the currently selected array of sub-nodes. |
| setChecked | set node to be checked or not, only works when `node-key` is assigned | (key/data, checked, deep) Accept three parameters: 1. node's key or data to be checked 2. a boolean typed parameter indicating checked or not. 3. a boolean typed parameter indicating deep or not. |
### Events
| Event Name | Description | Parameters |
|---------- |-------- |---------- |
| -------------- | ---------------------------------------- | ---------------------------------------- |
| node-click | triggers when a node is clicked | three parameters: node object corresponding to the node clicked, `node` property of TreeNode, TreeNode itself |
| check-change | triggers when the selected state of the node changes | three parameters: node object corresponding to the node whose selected state is changed, whether the node is selected, whether node's subtree has selected nodes |
| current-change | triggers when current node changes | two parameters: node object corresponding to the current node, `node` property of TreeNode |
| node-open | triggers when current node open | three parameters: node object corresponding to the node opened, `node` property of TreeNode, TreeNode itself |
| node-close | triggers when current node close | three parameters: node object corresponding to the node closed, `node` property of TreeNode, TreeNode itself |
