Examples of GraphDatabaseService

org.neo4j.graphdb.GraphDatabaseService
use Neo4j graphDb. {@link #shutdown() shutdown()}; GraphDatabaseService provides operations to {@link #createNode() createnodes}, {@link #getNodeById(long) get nodes given an id}, get the {@link #getReferenceNode() reference node} and ultimately {@link #shutdown() shutdown Neo4j}.
Please note that all operations that write to the graph must be invoked in a {@link Transaction transactional context}. Failure to do so will result in a {@link NotInTransactionException} being thrown.
