- Method Detail
  - getRoot
```
public FlatTreeNode<T> getRoot()
```
    Returns the root of the tree that contains this node. The root is the ancestor with no parent. This implementation have a runtime complexity of O(1).
    
    Specified by:
    
    getRoot in interface Tree<T,FlatTreeNode<T>>
    
    Returns:
    
    the root of the tree that contains this node
  - isRoot
```
public boolean isRoot()
```
    Description copied from interface: Tree
    
    Returns true if this node is the root of the tree.
    
    Specified by:
    
    isRoot in interface Tree<T,FlatTreeNode<T>>
    
    Returns:
    
    true if this node is the root of its tree, false otherwise
  - getValue
```
public T getValue()
```
    Description copied from interface: Tree
    
    Return the value of the current Tree node. The value may be null.
    
    Specified by:
    
    getValue in interface Tree<T,FlatTreeNode<T>>
    
    Returns:
    
    the value of the current Tree node
  - getParent
```
public Optional<FlatTreeNode<T>> getParent()
```
    Description copied from interface: Tree
    
    Return the parent node of this tree node.
    
    Specified by:
    
    getParent in interface Tree<T,FlatTreeNode<T>>
    
    Returns:
    
    the parent node, or Optional.empty() if this node is the root of the tree
  - getChild
```
public FlatTreeNode<T> getChild(int index)
```
    Description copied from interface: Tree
    
    Return the child node with the given index.
    
    Specified by:
    
    getChild in interface Tree<T,FlatTreeNode<T>>
    
    Parameters:
    
    index - the child index
    
    Returns:
    
    the child node with the given index
  - childCount
```
public int childCount()
```
    Description copied from interface: Tree
    
    Return the number of children this tree node consists of.
    
    Specified by:
    
    childCount in interface Tree<T,FlatTreeNode<T>>
    
    Returns:
    
    the number of children this tree node consists of
  - childOffset
```
public int childOffset()
```
    Return the index of the first child node in the underlying node array. -1 is returned if this node is a leaf.
    
    Specified by:
    
    childOffset in interface FlatTree<T,FlatTreeNode<T>>
    
    Returns:
    
    Return the index of the first child node in the underlying node array, or -1 if this node is a leaf
  - flattenedNodes
```
public ISeq<FlatTreeNode<T>> flattenedNodes()
```
    Description copied from interface: FlatTree
    
    Return the whole flattened tree values in breadth-first order. This is equivalent to
    final ISeq<T> seq = getRoot().breadthFirstStream() .collect(ISeq.toISeq());
    
    Specified by:
    
    flattenedNodes in interface FlatTree<T,FlatTreeNode<T>>
    
    Returns:
    
    the flattened tree values in breadth-first order
  - stream
```
public Stream<FlatTreeNode<T>> stream()
```
    Return a stream of all nodes of the whole underlying tree. This method call is equivalent to
    final Stream<FlatTreeNode<T>> nodes = getRoot().breadthFirstStream();
    
    Specified by:
    
    stream in interface Tree<T,FlatTreeNode<T>>
    
    Returns:
    
    a stream of all nodes of the whole underlying tree
    
    See Also:
    
    Tree.breadthFirstStream()
  - map
```
public <B> ISeq<B> map(Function<FlatTreeNode<T>,? extends B> mapper)
```
    Return a sequence of all mapped nodes of the whole underlying tree. This is a convenient method for
    final ISeq<B> seq = stream() .map(mapper) .collect(ISeq.toISeq())
    
    Type Parameters:
    
    B - the mapped type
    
    Parameters:
    
    mapper - the mapper function
    
    Returns:
    
    a sequence of all mapped nodes
  - identical
```
public boolean identical(Tree<?,?> other)
```
    Description copied from interface: Tree
    
    Tests whether this node is the same as the other node. The default implementation returns the object identity, this == other, of the two objects, but other implementations may use different criteria for checking the identity.
    
    Specified by:
    
    identical in interface Tree<T,FlatTreeNode<T>>
    
    Parameters:
    
    other - the other node
    
    Returns:
    
    true if the other node is the same as this node.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - of
```
public static <V> FlatTreeNode<V> of(Tree<? extends V,?> tree)
```
    Create a new FlatTreeNode from the given tree.
    
    Type Parameters:
    
    V - the tree value types
    
    Parameters:
    
    tree - the source tree
    
    Returns:
    
    a new FlatTreeNode from the given tree
