Warning: serialized objects of this class will not be compatible with future swing releases. The current serialization support is appropriate for short term storage or RMI between Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

TreePath()
Primarily provided for subclasses that don't wish to use the path ivar. |
|
TreePath(Object singlePath)
Constructs a TreePath when there is only item in the path. |
|
TreePath(Object[] path,
int length)
|
|
TreePath(Object[] path)
Constructs a path from an array of Objects, uniquely identifying the path from the root of the tree to a specific node, as returned by the tree's data model. |
|
TreePath(TreePath parent,
Object lastElement)
Constructs a TreePath this is the combination of all the path elements in parent with a last path component of
lastElement . |
Method Summary | |
boolean | equals(Object o)
Tests two TreePaths for equality by checking each element of the paths for equality. |
Object | getLastPathComponent()
Returns the last component of this path. |
TreePath | getParentPath()
Returns a path containing all the elements of the receiver, accept the last path component. |
Object[] | getPath()
Returns an array of Objects containing the components of this TreePath. |
Object | getPathComponent(int element)
Returns the path component at the specified index. |
int | getPathCount()
Returns the number of elements in the path. |
int | hashCode()
Returns the hashCode for the object. |
boolean | isDescendant(TreePath aTreePath)
Returns true if the specified node is a descendant of this TreePath. |
TreePath | pathByAddingChild(Object child)
Returns a new path containing all the elements of this receiver plus child . |
String | toString()
Returns a string that displays and identifies this object's properties. |

public TreePath(Object[] path)
The model is free to return an array of any Objects it needs to represent the path. The DefaultTreeModel returns an array of TreeNode objects. The first TreeNode in the path is the root of the tree, the last TreeNode is the node identified by the path.
