Constructor Detail

DefaultNodeSet

public DefaultNodeSet()

constructor for an empty node set.

DefaultNodeSet

public DefaultNodeSet(@Nonnull
                      E entity)

Parameters:

entity - the entity to be contained

DefaultNodeSet

public DefaultNodeSet(@Nonnull
                      Node<E> node)

Parameters:

node - the node to be contained

DefaultNodeSet

public DefaultNodeSet(@Nonnull
                      Set<Node<E>> nodes)

Parameters:

nodes - a set of nodes to be contained

Method Detail

getNodes

@Nonnull
public Set<Node<E>> getNodes()

Specified by:

getNodes in interface NodeSet<E extends OWLObject>

addEntity

public void addEntity(@Nonnull
                      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(@Nonnull
                    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(@Nonnull
                        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.

addSameEntities

public void addSameEntities(@Nonnull
                            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(@Nonnull
                                 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.
