com.lanceolav.jreftree
Class W3CMutableTreeNode  

java.lang.Object
  com.lanceolav.jreftree.W3CMutableTreeNode

All Implemented Interfaces:

javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode

---

public class W3CMutableTreeNode

extends java.lang.Object

implements javax.swing.tree.MutableTreeNode

W3CMutableTreeNode can be used in DefaultTreeModel (in addition to DefaultMutableTreeNode). It is only a thin wrapper around org.w3c.dom.Node, and owns only one instane of this class. It let's this node take care of all the bookkeeping with parents and children. The advantage is that we don't have to implement TreeModel, but can use the existing DefaultTreeModel, which has methods such as insertNodeInto(), which will dispatch the necessary events to update the tree.

Field Detail

domNode

private org.w3c.dom.Node domNode

---

typeName

private static final java.lang.String[] typeName

Constructor Detail

W3CMutableTreeNode

public W3CMutableTreeNode(org.w3c.dom.Node node)

Method Detail

getNode

private org.w3c.dom.Node getNode(javax.swing.tree.MutableTreeNode mtn)

---

getNode

private org.w3c.dom.Node getNode(javax.swing.tree.TreeNode tn)

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

insert

public void insert(javax.swing.tree.MutableTreeNode child,
                   int index)

Adds child to the receiver at index. child will be messaged with setParent.

Specified by:

insert in interface javax.swing.tree.MutableTreeNode

---

remove

public void remove(int index)

Removes the child at index from the receiver.

Specified by:

remove in interface javax.swing.tree.MutableTreeNode

---

remove

public void remove(javax.swing.tree.MutableTreeNode node)

Removes node from the receiver. setParent will be messaged on node.

Specified by:

remove in interface javax.swing.tree.MutableTreeNode

---

setUserObject

public void setUserObject(java.lang.Object object)

Resets the user object of the receiver to object.

Specified by:

setUserObject in interface javax.swing.tree.MutableTreeNode

---

removeFromParent

public void removeFromParent()

Removes the receiver from its parent.

Specified by:

removeFromParent in interface javax.swing.tree.MutableTreeNode

---

setParent

public void setParent(javax.swing.tree.MutableTreeNode newParent)

Sets the parent of the receiver to newParent.

Specified by:

setParent in interface javax.swing.tree.MutableTreeNode

---

getChildAt

Specified by:

getAllowsChildren in interface javax.swing.tree.TreeNode

---

isLeaf
