Class TransientRelationship

java.lang.Object

org.neo4j.ogm.mapper.TransientRelationship

public class TransientRelationship
extends Object

A TransientRelationship represents a relationship that is not yet established in the graph, where at least one of either the start node or end node is also a new object. Transient Relationships are recorded while the cypher request to save the domain model is being being constructed, and they are saved in the log of the transaction's current context for post-processing after the save request completes. If the save succeeds, the ids of the two ends of the actual relationship will now be fully known in the response. The start and end nodes of the transient relationship (which were previously place holders) can now be replaced with the correct node ids, and the new MappedRelationship established in the session's mappingContext.
