SceneGraphModel

public SceneGraphModel()

Method Detail

setRootNode

public void setRootNode(RootNode rootNode)

getRootNode

public RootNode getRootNode()

getRoot

public java.lang.Object getRoot()

Specified by:

getRoot in interface javax.swing.tree.TreeModel

addTreeModelListener

public void addTreeModelListener(javax.swing.event.TreeModelListener l)

Specified by:

addTreeModelListener in interface javax.swing.tree.TreeModel

removeTreeModelListener

public void removeTreeModelListener(javax.swing.event.TreeModelListener l)

Specified by:

removeTreeModelListener in interface javax.swing.tree.TreeModel

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath path,
                                java.lang.Object newValue)

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

getPathToRoot

public ActiveNode[] getPathToRoot(ActiveNode o)

Builds the parents of object up to and including the root object, where the original object is the last element in the returned array. The length of the returned array gives the object's depth in the tree.

Parameters:

o - the Object to get the path for

Returns:

an array of Object giving the path from the root to the specified object

getPathToRoot

public ActiveNode[] getPathToRoot(ActiveNode o,
                                  int depth)

Builds the parents of object up to and including the root object, where the original object is the last element in the returned array. The length of the returned array gives the object's depth in the tree.

Parameters:

o - the Object to get the path for

depth - an int giving the number of steps already taken towards the root (on recursive calls), used to size the returned array

Returns:

an array of Object giving the path from the root to the specified object

fireTreeChanged

public void fireTreeChanged(ActiveNode source,
                            java.lang.Object[] path,
                            int[] childIndices,
                            ActiveNode[] children)

Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

Parameters:

source - the node where the tree model has changed

path - the path to the root node

childIndices - the indices of the affected elements

children - the affected elements
