Constructor Detail

### UniqueFactory.UniqueNodeFactory

    public UniqueFactory.UniqueNodeFactory(Index<Node> index)

  Create a new `UniqueFactory` for nodes.

  Parameters:
    `index` - the index to store entities uniquely in.

### UniqueFactory.UniqueNodeFactory

    public UniqueFactory.UniqueNodeFactory(GraphDatabaseService graphdb,
                                           String index)

  Create a new `UniqueFactory` for nodes.

  Parameters:
    `graphdb` - the graph database to get the index from.
    `index` - the name of the index to store entities uniquely in.

Method Detail

### create

    protected Node create(Map<String,Object> properties)

  Default implementation of `UniqueFactory.create(Map)`, creates a plain node. Override to retrieve the node to add to the index by some other means than by creating it. For initialization of the `Node`, use the `UniqueFactory.initialize(PropertyContainer, Map)` method.

  Specified by:
    `create` in class `UniqueFactory<Node>`
  Parameters:
    `properties` - the properties that this entity will is to be indexed uniquely with.
  Returns:
    the entity to add to the index.
  See Also:
    `UniqueFactory.create(Map)`, `UniqueFactory.initialize(PropertyContainer, Map)`

### delete

    protected void delete(Node node)

  Default implementation of `UniqueFactory.delete(PropertyContainer)`. Invokes `Node.delete()`.

  Specified by:
    `delete` in class `UniqueFactory<Node>`
  Parameters:
    `node` - the entity that was created but was not added to the index.
  See Also:
    `UniqueFactory.delete(PropertyContainer)`
