  MutableTreeNode

All Known Implementing Classes:
  AbstractDocument.AbstractElement, DefaultMutableTreeNode

public interface TreeNode

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

For further information and examples of using tree nodes, see How to Use Tree Nodes in The Java Tutorial.

Method Summary
`Enumeration` | `children()` Returns the children of the receiver as an `Enumeration`.
`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 `TreeNode`s the receiver contains.
`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

### getChildAt

    public TreeNode getChildAt(int childIndex)

  Returns the child `TreeNode` at index `childIndex`.

### getChildCount

    public int getChildCount()
