Adds a PropertyChangeListener to the listener list.

  Adds a PropertyChangeListener to the listener list. The listener is registered for all properties.

A PropertyChangeEvent will get fired when the selection mode changes.
Parameters:
- listener - the PropertyChangeListener to be added

  Adds path to the current selection.

  Adds path to the current selection. If path is not currently
in the selection the TreeSelectionListeners are notified. This has
no effect if path is null.
Parameters:
- path - the new path to add to the current selection

  Adds paths to the current selection.

  Adds paths to the current selection. If any of the paths in paths are not currently in the selection the TreeSelectionListeners are notified. This has no effect if paths is null.

The lead path is set to the last element in paths.

If the selection mode is CONTIGUOUS_TREE_SELECTION, and adding the new paths would make the selection discontiguous. Then two things can result: if the TreePaths in paths are contiguous, then the selection becomes these TreePaths, otherwise the TreePaths aren't contiguous and the selection becomes the first TreePath in paths.
Parameters:
- paths - the new path to add to the current selection

  Adds x to the list of listeners that are notified each time the set of selected TreePaths changes.

  Adds x to the list of listeners that are notified each time the
set of selected TreePaths changes.
Parameters:
- x - the new listener to be added

Returns true if the paths are contiguous, or this object has no RowMapper.

  Used to test if a particular set of TreePaths can be added.

  Used to test if a particular set of TreePaths can
be added. This will return true if paths is null (or
empty), or this object has no RowMapper, or nothing is currently selected,
or the selection mode is DISCONTIGUOUS_TREE_SELECTION, or
adding the paths to the current selection still results in a
contiguous set of TreePaths.

  Returns true if the paths can be removed without breaking the continuity of the model.

  Returns true if the paths can be removed without breaking the
continuity of the model.
This is rather expensive.

  Empties the current selection.

  Empties the current selection. If this represents a change in the
current selection, the selection listeners are notified.

  Returns a clone of this object with the same selection.

  Returns a clone of this object with the same selection.
This method does not duplicate
selection listeners and property listeners.
Throws:
- CloneNotSupportedException - never thrown by instances of this class

  Notifies all listeners that are registered for tree selection events on this object.

  Notifies all listeners that are registered for
tree selection events on this object.

  Returns the last path that was added.

  Returns the last path that was added. This may differ from the
leadSelectionPath property maintained by the JTree.

  Returns the lead selection index.

  Returns the lead selection index. That is the last index that was
added.

  Returns an array of all the objects currently registered as FooListeners upon this model.

  Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultTreeSelectionModel m for its tree selection listeners with the following code:

TreeSelectionListener[] tsls = (TreeSelectionListener[])(m.getListeners(TreeSelectionListener.class));

If no such listeners exist, this method returns an empty array.
Returns: an array of all objects registered as FooListeners on this component, or an empty array if no such listeners have been added
Parameters:
- listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
Throws:
- ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener

  Returns the largest value obtained from the RowMapper for the current set of selected TreePaths.

  Returns the largest value obtained from the RowMapper for the
current set of selected TreePaths. If nothing is selected,
or there is no RowMapper, this will return -1.

  Returns the smallest value obtained from the RowMapper for the current set of selected TreePaths.

  Returns the smallest value obtained from the RowMapper for the
current set of selected TreePaths. If nothing is selected,
or there is no RowMapper, this will return -1.

  Returns an array of all the property change listeners registered on this DefaultTreeSelectionModel.

  Returns an array of all the property change listeners
registered on this DefaultTreeSelectionModel.
Returns: all of this model's PropertyChangeListeners or an empty array if no property change listeners are currently registered
Since: 1.4

Returns the RowMapper instance that is able to map a TreePath to a row.

Returns the number of paths that are selected.

Returns the selection mode, one of SINGLE_TREE_SELECTION, DISCONTIGUOUS_TREE_SELECTION or CONTIGUOUS_TREE_SELECTION.

  Returns the first path in the selection.

  Returns the first path in the selection. This is useful if there
if only one item currently selected.

  Returns the paths in the selection.

  Returns the paths in the selection. This will return null (or an
empty array) if nothing is currently selected.

  Returns all of the currently selected rows.

  Returns all of the currently selected rows. This will return
null (or an empty array) if there are no selected TreePaths or
a RowMapper has not been set.
This may return an array of length less that than of the selected
TreePaths if some of the rows are not visible (that is the
RowMapper returned -1 for the row corresponding to the TreePath).

  Returns an array of all the tree selection listeners registered on this model.

  Returns an array of all the tree selection listeners
registered on this model.
Returns: all of this model's TreeSelectionListeners or an empty array if no tree selection listeners are currently registered
Since: 1.4

  Makes sure the currently selected TreePaths are valid for the current selection mode.

  Makes sure the currently selected TreePaths are valid for the current selection mode. If the selection mode is CONTIGUOUS_TREE_SELECTION and a RowMapper exists, this will make sure all the rows are contiguous, that is, when sorted all the rows are in order with no gaps. If the selection isn't contiguous, the selection is reset to contain the first set, when sorted, of contiguous rows.

If the selection mode is SINGLE_TREE_SELECTION and more than one TreePath is selected, the selection is reset to contain the first path currently selected.

  This method is obsolete and its implementation is now a noop.

  This method is obsolete and its implementation is now a noop. It's
still called by setSelectionPaths and addSelectionPaths, but only
for backwards compatability.

Returns true if the path, path, is in the current selection.

Returns true if the row identified by row is selected.

Returns true if the selection is currently empty.

  Notifies listeners of a change in path.

  Notifies listeners of a change in path. changePaths should contain
instances of PathPlaceHolder.

  Removes a PropertyChangeListener from the listener list.

  Removes a PropertyChangeListener from the listener list.
This removes a PropertyChangeListener that was registered
for all properties.
Parameters:
- listener - the PropertyChangeListener to be removed

  Removes path from the selection.

  Removes path from the selection. If path is in the selection
The TreeSelectionListeners are notified. This has no effect if
path is null.
Parameters:
- path - the path to remove from the selection

  Removes paths from the selection.

  Removes paths from the selection. If any of the paths in paths
are in the selection the TreeSelectionListeners are notified.
This has no effect if paths is null.
Parameters:
- paths - the paths to remove from the selection

  Removes x from the list of listeners that are notified each time the set of selected TreePaths changes.

  Removes x from the list of listeners that are notified each time
the set of selected TreePaths changes.
Parameters:
- x - the listener to remove

  Updates this object's mapping from TreePath to rows.

  Updates this object's mapping from TreePath to rows. This should be invoked when the mapping from TreePaths to integers has changed (for example, a node has been expanded).

You do not normally have to call this, JTree and its associated Listeners will invoke this for you. If you are implementing your own View class, then you will have to invoke this.

This will invoke insureRowContinuity to make sure the currently selected TreePaths are still valid based on the selection mode.

  Sets the RowMapper instance.

  Sets the RowMapper instance. This instance is used to determine
the row for a particular TreePath.

  Sets the selection model, which must be one of SINGLE_TREE_SELECTION, CONTIGUOUS_TREE_SELECTION or DISCONTIGUOUS_TREE_SELECTION.

  Sets the selection model, which must be one of SINGLE_TREE_SELECTION, CONTIGUOUS_TREE_SELECTION or DISCONTIGUOUS_TREE_SELECTION. If mode is not one of the defined value, DISCONTIGUOUS_TREE_SELECTION is assumed.

This may change the selection if the current selection is not valid for the new mode. For example, if three TreePaths are selected when the mode is changed to SINGLE_TREE_SELECTION, only one TreePath will remain selected. It is up to the particular implementation to decide what TreePath remains selected.

Setting the mode to something other than the defined types will result in the mode becoming DISCONTIGUOUS_TREE_SELECTION.

  Sets the selection to path.

  Sets the selection to path. If this represents a change, then
the TreeSelectionListeners are notified. If path is
null, this has the same effect as invoking clearSelection.
Parameters:
- path - new path to select

  Sets the selection to the paths in paths.

  Sets the selection to the paths in paths. If this represents a change the TreeSelectionListeners are notified. Potentially paths will be held by this object; in other words don't change any of the objects in the array once passed in.

If paths is null, this has the same effect as invoking clearSelection.

The lead path is set to the last path in pPaths.

If the selection mode is CONTIGUOUS_TREE_SELECTION, and adding the new paths would make the selection discontiguous, the selection is reset to the first TreePath in paths.
Parameters:
- pPaths - new selection

  Returns a string that displays and identifies this object's properties.

  Returns a string that displays and identifies this
object's properties.
Returns: a String representation of this object

Updates the leadIndex instance variable.
