public class DefaultTreeModel

extends Object

implements Serializable, TreeModel

asksAllowsChildren

Whether or not isLeaf or getAllowsChildren is messaged to determine leafness with regard to TreeModel.

listenerList

Listeners.

root

Root of the tree.

DefaultTreeModel(TreeNode)

DefaultTreeModel(TreeNode, boolean)

addTreeModelListener(TreeModelListener)

asksAllowsChildren()

Returns whether or not to test leafness by asking getAllowsChildren() or isLeaf() to the TreeNodes.

fireTreeNodesChanged(Object, Object[], int[], Object[])

fireTreeNodesRemoved(Object, Object[], int[], Object[])

fireTreeStructureChanged(Object, Object[], int[], Object[])

getChild(Object, int)

getChildCount(Object)

getIndexOfChild(Object, Object)

getPathToRoot(TreeNode)

Builds the parents of child up to, and including, the root node.

getPathToRoot(TreeNode, int)

getRoot()

insertNodeInto(MutableTreeNode, MutableTreeNode, int)

Invoked this to insert newChild at location index in parents children.

isLeaf(Object)

nodeChanged(TreeNode)

Invoke this method after you've changed how node is to be represented in the tree.

nodesChanged(TreeNode, int[])

Invoke this method after you've changed how the children identified by childIndicies are to be represented in the tree.

nodeStructureChanged(TreeNode)

Invoke this method if you've totally changed the children of node and its childrens children...

nodesWereInserted(TreeNode, int[])

Invoke this method after you've inserted some TreeNodes into node.

nodesWereRemoved(TreeNode, int[], Object[])

Invoke this method after you've removed some TreeNodes from node.

reload()

Invoke this method if you've modified the TreeNodes upon which this model depends.

reload(TreeNode)

Invoke this method if you've modified the TreeNodes upon which this model depends.

removeNodeFromParent(MutableTreeNode)

Message this to remove node from its parent.

removeTreeModelListener(TreeModelListener)

setAsksAllowsChildren(boolean)

Sets whether or not to test leafness by asking getAllowsChildren() or isLeaf() to the TreeNodes.

valueForPathChanged(TreePath, Object)

This sets the user object of the TreeNode identified by path and posts a node changed.

 protected TreeNode root

Root of the tree.

 protected EventListenerList listenerList

Listeners.

 protected boolean asksAllowsChildren

Whether or not isLeaf or getAllowsChildren is messaged to determine leafness with regard to TreeModel.

 public DefaultTreeModel(TreeNode root)

 public DefaultTreeModel(TreeNode root,
                         boolean asksAllowsChildren)

 public void setAsksAllowsChildren(boolean newValue)

Sets whether or not to test leafness by asking getAllowsChildren() or isLeaf() to the TreeNodes. If newvalue is true, getAllowsChildren() is messaged, otherwise isLeaf() is messaged.

 public boolean asksAllowsChildren()

Returns whether or not to test leafness by asking getAllowsChildren() or isLeaf() to the TreeNodes.

 public Object getRoot()

 public int getIndexOfChild(Object parent,
                            Object child)

 public Object getChild(Object parent,
                        int index)

 public int getChildCount(Object parent)

 public boolean isLeaf(Object node)

 public void reload()

Invoke this method if you've modified the TreeNodes upon which this model depends. The model will notify all of its listeners that the model has changed.

 public void valueForPathChanged(TreePath path,
                                 Object newValue)

This sets the user object of the TreeNode identified by path and posts a node changed. If you use custom user objects in the TreeModel you're going to need to subclass this and set the user object of the changed node to something meaningful.

 public void insertNodeInto(MutableTreeNode newChild,
                            MutableTreeNode parent,
                            int index)

Invoked this to insert newChild at location index in parents children. This will then message nodesWereInserted to create the appropriate event. This is the preferred way to add children as it will create the appropriate event.

 public void removeNodeFromParent(MutableTreeNode node)

Message this to remove node from its parent. This will message nodesWereRemoved to create the appropriate event. This is the preferred way to remove a node as it handles the event creation for you.

 public void nodeChanged(TreeNode node)

Invoke this method after you've changed how node is to be represented in the tree.

 public void reload(TreeNode node)

Invoke this method if you've modified the TreeNodes upon which this model depends. The model will notify all of its listeners that the model has changed below the node node (PENDING).

 public void nodesWereInserted(TreeNode node,
                               int childIndices[])

Invoke this method after you've inserted some TreeNodes into node. childIndices should be the index of the new elements and must be sorted in ascending order.

 public void nodesWereRemoved(TreeNode node,
                              int childIndices[],
                              Object removedChildren[])

Invoke this method after you've removed some TreeNodes from node. childIndices should be the index of the removed elements and must be sorted in ascending order. And removedChildren should be the array of the children objects that were removed.

 public void nodesChanged(TreeNode node,
                          int childIndices[])

Invoke this method after you've changed how the children identified by childIndicies are to be represented in the tree.

 public void nodeStructureChanged(TreeNode node)

Invoke this method if you've totally changed the children of node and its childrens children... This will post a treeStructureChanged event.

 public TreeNode[] getPathToRoot(TreeNode child)

Builds the parents of child up to, and including, the root node. child will be the last element in the returned array.

 protected TreeNode[] getPathToRoot(TreeNode aNode,
                                    int depth)

 public void addTreeModelListener(TreeModelListener l)

 public void removeTreeModelListener(TreeModelListener l)

 protected void fireTreeNodesChanged(Object source,
                                     Object path[],
                                     int childIndices[],
                                     Object children[])

                                      int childIndices[],
                                      Object children[])

                                         Object path[],
                                         int childIndices[],
