Method Summary
public static  DefaultMutableTreeNodecopy(DefaultMutableTreeNode node)
     Recursively copies node using its clone() method (which, unless overridden, is a shallow copy).
public  DefaultMutableTreeNodegetRoot()
     Returns the root of the tree or null if there is none.
public  voidinsertAfter(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)
     Inserts node after dest, throwing an exception if dest is the root.
public  voidinsertBefore(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)
     Inserts node before dest, throwing an exception if dest is the root.
public  voidinsertUnder(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)
     Inserts node under dest.
public  voidmoveAfter(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)
     Moves node after dest.
public  voidmoveBefore(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)
     Moves node after dest.
public  voidmoveUnder(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)
     Moves node under dest.
public  voidremove(DefaultMutableTreeNode node)
     Removes node and all of its children from the tree.
public  voidremoveAndPromoteChildren(DefaultMutableTreeNode node)
     Removes node, adding its child nodes to the parent node.
public  voidsetRoot(DefaultMutableTreeNode link)
     Sets the root of the tree; note: any existing nodes will be lost.
public static  voidsort(DefaultMutableTreeNode node, Comparator comparator)
     Sorts the children of node using comparator; comparator should expect DefaultMutableTreeNodes to be passed to it.
public  StringvalidateMove(DefaultMutableTreeNode node, DefaultMutableTreeNode dest, String position)
     Confirms if dest can be positioned position (one of the POSITION_ constants) near node successfully.

Method Detail
copy
public static DefaultMutableTreeNode copy(DefaultMutableTreeNode node)(Code)
Recursively copies node using its clone() method (which, unless overridden, is a shallow copy).



getRoot
public DefaultMutableTreeNode getRoot()(Code)
Returns the root of the tree or null if there is none.



insertAfter
public void insertAfter(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)(Code)
Inserts node after dest, throwing an exception if dest is the root.



insertBefore
public void insertBefore(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)(Code)
Inserts node before dest, throwing an exception if dest is the root.



insertUnder
public void insertUnder(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)(Code)
Inserts node under dest.



moveAfter
public void moveAfter(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)(Code)
Moves node after dest. An exception is thrown if node is an ancestor of dest, or if dest is the root.



moveBefore
public void moveBefore(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)(Code)
Moves node after dest. An exception is thrown if node is an ancestor of dest, or if dest is the root.



moveUnder
public void moveUnder(DefaultMutableTreeNode dest, DefaultMutableTreeNode node)(Code)
Moves node under dest. An exception is thrown if node is an ancestor of dest.



remove
public void remove(DefaultMutableTreeNode node)(Code)
Removes node and all of its children from the tree.



removeAndPromoteChildren
public void removeAndPromoteChildren(DefaultMutableTreeNode node)(Code)
Removes node, adding its child nodes to the parent node. If node is the root, its first child is promoted to root, adding its children after the root's remaining children.



setRoot
public void setRoot(DefaultMutableTreeNode link)(Code)
Sets the root of the tree; note: any existing nodes will be lost.



sort
public static void sort(DefaultMutableTreeNode node, Comparator comparator)(Code)
Sorts the children of node using comparator; comparator should expect DefaultMutableTreeNodes to be passed to it.



validateMove
public String validateMove(DefaultMutableTreeNode node, DefaultMutableTreeNode dest, String position)(Code)
Confirms if dest can be positioned position (one of the POSITION_ constants) near node successfully. If so, VALIDMOVE is returned, otherwise on of the INVALIDMOVE_ constants is returned.
