## Uses of DefaultMutableTreeNode in javax.swing.tree

Methods in javax.swing.tree that return DefaultMutableTreeNode
Modifier and Type | Method | Description

`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getFirstLeaf()` | Finds and returns the first leaf that is a descendant of this node -- either this node or its first child's first leaf.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getLastLeaf()` | Finds and returns the last leaf that is a descendant of this node -- either this node or its last child's last leaf.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getNextLeaf()` | Returns the leaf after this node or null if this node is the last leaf in the tree.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getNextNode()` | Returns the node that follows this node in a preorder traversal of this node's tree.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getNextSibling()` | Returns the next sibling of this node in the parent's children array.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getPreviousLeaf()` | Returns the leaf before this node or null if this node is the first leaf in the tree.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getPreviousNode()` | Returns the node that precedes this node in a preorder traversal of this node's tree.
`DefaultMutableTreeNode` | DefaultMutableTreeNode.`getPreviousSibling()` | Returns the previous sibling of this node in the parent's children array.

Methods in javax.swing.tree with parameters of type DefaultMutableTreeNode
Modifier and Type | Method | Description
--- | --- | ---
`TreeNode` | DefaultMutableTreeNode.`getSharedAncestor​(DefaultMutableTreeNode aNode)` | Returns the nearest common ancestor to this node and `aNode`.
`boolean` | DefaultMutableTreeNode.`isNodeDescendant​(DefaultMutableTreeNode anotherNode)` | Returns true if `anotherNode` is a descendant of this node -- if it is this node, one of this node's children, or a descendant of one of this node's children.
`boolean` | DefaultMutableTreeNode.`isNodeRelated​(DefaultMutableTreeNode aNode)` | Returns true if and only if `aNode` is in the same tree as this node.
