  • Method Details

    • 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:

    • 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:

    • 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.
