From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public void treeNodesChanged (TreeModelEvent e)

Invoked after a node (or a set of siblings) has changed in some way. The node(s) have not changed locations in the tree or altered their children arrays, but other attributes have changed and may affect presentation. Example: the name of a file has changed, but it is in the same location in the file system.

To indicate the root has changed, childIndices and children will be null.

Use e.getPath() to get the parent of the changed node(s). e.getChildIndices() returns the index(es) of the changed node(s).

public void treeNodesInserted (TreeModelEvent e)

Invoked after nodes have been inserted into the tree.

Use e.getPath() to get the parent of the new node(s). e.getChildIndices() returns the index(es) of the new node(s) in ascending order.

public void treeNodesRemoved (TreeModelEvent e)

Invoked after nodes have been removed from the tree. Note that if a subtree is removed from the tree, this method may only be invoked once for the root of the removed subtree, not once for each individual set of siblings removed.

Use e.getPath() to get the former parent of the deleted node(s). e.getChildIndices() returns, in ascending order, the index(es) the node(s) had before being deleted.

public void treeStructureChanged (TreeModelEvent e)

Invoked after the tree has drastically changed structure from a given node down. If the path returned by e.getPath() is of length one and the first element does not identify the current root node the first element should become the new root of the tree.

Use e.getPath() to get the path to the node. e.getChildIndices() returns null.
