Field

Vector	children array of children, may be null if this node has no children

Constructor

	DefaultMutableTreeNode(Object userObject) Creates a tree node with no parent, no children, but which allows children, and initializes it with the specified user object.
	DefaultMutableTreeNode() Creates a tree node that has no parent and no children, but which allows children.
	DefaultMutableTreeNode(Object userObject, boolean allowsChildren) Creates a tree node with no parent, no children, initialized with the specified user object, and that allows children only if specified.

Method

void	add(MutableTreeNode newChild) Removes `newChild` from its parent and makes it a child of this node by adding it to the end of this node's child array.
Enumeration	breadthFirstEnumeration() Creates and returns an enumeration that traverses the subtree rooted at this node in breadth-first order.
Object	clone() Overridden to make clone public.
Enumeration	depthFirstEnumeration() Creates and returns an enumeration that traverses the subtree rooted at this node in depth-first order.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
boolean	getAllowsChildren() Returns true if this node is allowed to have children.
TreeNode	getChildAfter(TreeNode aChild) Returns the child in this node's child array that immediately follows `aChild`, which must be a child of this node.
TreeNode	getChildAt(int index) Returns the child at the specified index in this node's child array.
TreeNode	getChildBefore(TreeNode aChild) Returns the child in this node's child array that immediately precedes `aChild`, which must be a child of this node.
int	getChildCount() Returns the number of children of this node.
Class	getClass() Returns the runtime class of this Object .
int	getDepth() Returns the depth of the tree rooted at this node -- the longest distance from this node to a leaf.
TreeNode	getFirstChild() Returns this node's first child.
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.
int	getIndex(TreeNode aChild) Returns the index of the specified child in this node's child array.
TreeNode	getLastChild() Returns this node's last child.
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.
int	getLevel() Returns the number of levels above this node -- the distance from the root to this node.
DefaultMutableTreeNode	getNextLeaf() Returns the leaf after this node or null if this node is the last leaf in the tree.
DefaultMutableTreeNode	getNextNode() Returns the node that follows this node in a preorder traversal of this node's tree.
DefaultMutableTreeNode	getNextSibling() Returns the next sibling of this node in the parent's children array.
TreeNode	getParent() Returns this node's parent or null if this node has no parent.
TreeNode[]	getPath() Returns the path from the root, to get to this node.
DefaultMutableTreeNode	getPreviousNode() Returns the node that precedes this node in a preorder traversal of this node's tree.
DefaultMutableTreeNode	getPreviousSibling() Returns the previous sibling of this node in the parent's children array.
TreeNode	getRoot() Returns the root of the tree that contains this node.
Object	getUserObject() Returns this node's user object.
Object[]	getUserObjectPath() Returns the user object path, from the root, to get to this node.
void	insert(MutableTreeNode newChild, int childIndex) Removes `newChild` from its present parent (if it has a parent), sets the child's parent to this node, and then adds the child to this node's child array at index `childIndex`.
boolean	isLeaf() Returns true if this node has no children.
boolean	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	isRoot() Returns true if this node is the root of the tree.
Enumeration	preorderEnumeration() Creates and returns an enumeration that traverses the subtree rooted at this node in preorder.
void	remove(int childIndex) Removes the child at the specified index from this node's children and sets that node's parent to null.
void	remove(MutableTreeNode aChild) Removes `aChild` from this node's child array, giving it a null parent.
void	removeAllChildren() Removes all of this node's children, setting their parents to null.
void	removeFromParent() Removes the subtree rooted at this node from the tree, giving this node a null parent.
void	setAllowsChildren(boolean allows) Determines whether or not this node is allowed to have children.
void	setUserObject(Object userObject) Sets the user object for this node to `userObject`.
String	toString() Returns the result of sending `toString()` to this node's user object, or the empty string if the node has no user object.
