- Method Detail
  - nodes
```
public Stream<Node<E>> nodes()
```
    Description copied from interface: NodeSet
    
    Gets the Nodes contained in this NodeSet.
    
    Specified by:
    
    nodes in interface NodeSet<E extends OWLObject>
    
    Returns:
    
    stream of Nodes contained in this NodeSet.
  - addEntity
```
public void addEntity(E entity)
```
    Adds an entity to this NodeSet by wrapping it in a Node.
    
    Parameters:
    
    entity - The entity to be added. The entity will be wrapped in the Node and the Node added to this set. Must not be null.
    
    Throws:
    
    NullPointerException - if entity is null.
  - addNode
```
public void addNode(Node<E> node)
```
    Adds a Node to this set.
    
    Parameters:
    
    node - The Node to be added.
    
    Throws:
    
    NullPointerException - if entity is null.
  - addAllNodes
```
public void addAllNodes(Collection<Node<E>> nodeset)
```
    Adds a collection of Nodes to this set.
    
    Parameters:
    
    nodeset - The Nodes to be added. Note that if the collection is not a set then duplicate Nodes will be filtered out.
  - addAllNodes
```
public void addAllNodes(Stream<Node<E>> nodeset)
```
    Adds a collection of Nodes to this set.
    
    Parameters:
    
    nodeset - The Nodes to be added. Note that if the collection is not a set then duplicate Nodes will be filtered out.
  - addSameEntities
```
public void addSameEntities(Set<E> entities)
```
    Adds the set of entities as a Node to this set.
    
    Parameters:
    
    entities - The set of entities to be added. The entities will be wrapped in a Node which will be added to this NodeSet.
  - addDifferentEntities
```
public void addDifferentEntities(Set<E> entities)
```
    Adds the specified entities as Nodes to this set.
    
    Parameters:
    
    entities - The entities to be added. Each entity will be wrapped in a Node which will then be added to this NodeSet.
  - entities
```
public Stream<E> entities()
```
    Description copied from interface: NodeSet
    
    A convenience method that gets all of the entities contained in the Nodes in this NodeSet.
    
    Specified by:
    
    entities in interface NodeSet<E extends OWLObject>
    
    Returns:
    
    The union of the entities contained in the Nodes in this NodeSet.
  - isEmpty
```
public boolean isEmpty()

    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
```
public boolean isSingleton()
```
    Description copied from interface: NodeSet
    
    Determines if this NodeSet is a singleton. A NodeSet is a singleton if it contains only one Node.
    
    Specified by:
    
    isSingleton in interface NodeSet<E extends OWLObject>
    
    Returns:
    
    true if this NodeSet is a singleton, otherwise false.

    Specified by:
    
    isTopSingleton in interface NodeSet<E extends OWLObject>
    
    Returns:
    
    true if this NodeSet is a singleton that contains only the top node, and false otherwise.
    
    See Also:
    
    Node.isTopNode()
  - isBottomSingleton
```
