Neo4jWrapper

trait Neo4jWrapper extends GraphDatabaseServiceProvider with Neo4jWrapperImplicits

Extend your class with this trait to get really neat new notation for creating new relationships. For example, ugly Java-esque code like: 

val knows = DynamicRelationshipType.withName("KNOWS")
start.createRelationshipTo(intermediary, knows)
intermediary.createRelationshipTo(end, knows)

can be replaced with a beautiful Scala one-liner: 

start --> "KNOWS" --> intermediary --> "KNOWS" --> end

  21. def getRelationshipTypes(implicit ds: DatabaseService): Iterable[RelationshipType]

    Returns all relationship types currently in the underlying store.

    Returns all relationship types currently in the underlying store. Relationship types are added to the underlying store the first time they are used in a successfully commited Node#createRelationshipTo node.createRelationshipTo(...). Note that this method is guaranteed to return all known relationship types, but it does not guarantee that it won't return more than that (e.g. it can return "historic" relationship types that no longer have any relationships in the node space).

    returns

    all relationship types in the underlying store
