Interface TreeNode

All Known Subinterfaces:

MutableTreeNode

All Known Implementing Classes:

DefaultMutableTreeNode

public interface TreeNode

Defines the requirements for an object that can be used as a tree node in a Tree.

Method Summary

java.util.Enumeration	children() Returns the children of the reciever as an Enumeration.
java.lang.String	getActionCommand() Returns the Action command string associated with this node
boolean	getAllowsChildren() Returns true if the receiver allows children.
TreeNode	getChildAt(int childIndex) Returns the child TreeNode at index childIndex.
int	getChildCount() Returns the number of children TreeNodes the receiver contains.
int	getId() Returns the unique Id of the TreeNode Using System.identityHashCode(node) might be a good way to implement this;
int	getIndex(TreeNode node) Returns the index of node in the receivers children.
TreeNode	getParent() Returns the parent TreeNode of the receiver.
boolean	isLeaf() Returns true if the receiver is a leaf.

Method Detail

children

public java.util.Enumeration children()

Returns the children of the reciever as an Enumeration.

getActionCommand

public java.lang.String getActionCommand()

Returns the Action command string associated with this node

getAllowsChildren

public boolean getAllowsChildren()

Returns true if the receiver allows children.

getChildAt

public TreeNode getChildAt(int childIndex)

Returns the child TreeNode at index childIndex.

getChildCount

public int getChildCount()

Returns the number of children TreeNodes the receiver contains.

getId

public int getId()

Returns the unique Id of the TreeNode

Using System.identityHashCode(node) might be a good way to implement this;

getIndex

public int getIndex(TreeNode node)

Returns the index of node in the receivers children. If the receiver does not contain node, -1 will be returned.

getParent

public TreeNode getParent()

Returns the parent TreeNode of the receiver.

isLeaf

public boolean isLeaf()

Returns true if the receiver is a leaf.
