- Method Detail
  - getFlattened
```
default Set<E> getFlattened()
```
    A convenience method that gets all of the entities contained in the Nodes in this NodeSet.
    
    Returns:
    
    The union of the entities contained in the Nodes in this NodeSet. The set that is returned is a copy; modifications to the returned set will not be reflected in this object.
  - entities
```
Stream<E> entities()
```
    A convenience method that gets all of the entities contained in the Nodes in this NodeSet.
    
    Returns:
    
    The union of the entities contained in the Nodes in this NodeSet.
  - isEmpty
```
boolean isEmpty()
```
    Returns:
    
    true if the node set is empty
  - containsEntity
```
boolean containsEntity(E e)
```
    A convenience method that determines if this NodeSet contains a specific entity.
    
    Parameters:
    
    e - The entity to test for
    
    Returns:
    
    true if this NodeSet contains a Node that contains the entity, e, and false if this NodeSet does not contain a Node that contains the entity, e.
  - isSingleton
```
boolean isSingleton()
```
    Determines if this NodeSet is a singleton. A NodeSet is a singleton if it contains only one Node.
    
    Returns:
    
    true if this NodeSet is a singleton, otherwise false.
  - isTopSingleton
```
boolean isTopSingleton()
```
    Determines if this NodeSet is a singleton node that only contains the top node (in a hierarchy).
    
    Returns:
    
    true if this NodeSet is a singleton that contains only the top node, and false otherwise.
    
    See Also:
    
    Node.isTopNode()
  - isBottomSingleton
```
boolean isBottomSingleton()
```
    Determines if this NodeSet is a singleton that only contains the bottom node (in a hierarchy).
    
    Returns:
    
    true if this NodeSet is a singleton that only contains a node that is the bottom node, otherwise false
    
    See Also:
    
    Node.isBottomNode()
  - getNodes
```
default Set<Node<E>> getNodes()
```
    Gets the Nodes contained in this NodeSet.
    
    Returns:
    
    The set of Nodes contained in this NodeSet. The set that is returned is a copy; modifications to the returned set will not be reflected in this object.
  - nodes
```
Stream<Node<E>> nodes()
```
    Gets the Nodes contained in this NodeSet.
    
    Returns:
    
    stream of Nodes contained in this NodeSet.
