Class Neo4jTemplate

java.lang.Object

org.springframework.data.neo4j.support.Neo4jTemplate

All Implemented Interfaces:

Aware, ApplicationContextAware, Neo4jOperations

public class Neo4jTemplate
extends Object
implements Neo4jOperations, ApplicationContextAware

Mediator class for the graph related services like the GraphDatabaseService, the used TypeRepresentationStrategy, entity instantiators for nodes and relationships as well as a spring conversion service.

It delegates the appropriate methods to those services. The services are not intended to be accessible from outside.
