java.lang.Objectjavax.swing.tree.TreePath
public class TreePath
A TreePath represents a sequence of tree elements that form
a path starting from the root of a tree. A tree element can be represented
by any Object.
| Constructor Summary | |
|---|---|
protected |
TreePath()
Default constructor. |
|
TreePath(Object element)
Creates a new path from a single element. |
|
TreePath(Object[] path)
Creates a path from the list of objects representing tree elements. |
protected |
TreePath(Object[] path,
int length)
Creates a new tree path using the first length elements
from the given array. |
protected |
TreePath(TreePath path,
Object element)
Creates a new tree path by adding the specified element to
the path. |
| Method Summary | |
|---|---|
boolean |
equals(Object object)
Tests this path for equality with an arbitrary object. |
Object |
getLastPathComponent()
Returns the last object in the path. |
TreePath |
getParentPath()
Returns the parent path, which is a path containing all the same elements as this path, except for the last one. |
Object[] |
getPath()
Returns an array containing the path elements. |
Object |
getPathComponent(int position)
Returns the element at the specified position in the path. |
int |
getPathCount()
Returns the number of elements in the path. |
int |
hashCode()
Returns a hashcode for the path. |
boolean |
isDescendant(TreePath path)
Returns true if path is a descendant of this
path, and false otherwise. |
TreePath |
pathByAddingChild(Object element)
Creates a new path that is equivalent to this path plus the specified element. |
String |
toString()
Returns a string representation of this path. |
