  - getValue
```
T getValue()
```
    Returns the value represented by this node.
  - isLeaf
```
boolean isLeaf()
```
    If true, then this node is a leaf node, which never has children (i.e., a file). If false, the node may have children (i.e., a folder).
    
    Returns:
    
    true for leaf nodes, false for folder nodes

    TreeModelAdapter.isLeaf(Object)
  - getHasChildren
```
boolean getHasChildren()
```
    Returns true if this non-leaf node has child nodes. This will not be invoked for leaf nodes.

  - getChildren
```
List<TreeNode<T>> getChildren()
```
    Returns the actual children of this non-leaf node, as additional nodes.

    TreeModelAdapter.getChildren(Object)
  - getLabel
```
String getLabel()
```
    Returns a textual label for the node. Not all UIs will make use of the label, but default UIs will.
