Class RelationshipAliasTree

java.lang.Object

org.hibernate.ogm.datastore.neo4j.query.parsing.impl.RelationshipAliasTree

public class RelationshipAliasTree
extends Object

Tree structure that can be used to store alias of the relationships in Neo4j.

For example, a path to two properties like:

1. n.first.anotherEmbedded
2. n.association.anotherEmbedded

Might be represented with the following structure:

 n (alias = n)|- first (alias = _n0)  -- anotherEmbedded (alias = _n1)
              |
              -- association (alias = _n2) -- anotherEmbedded (alias = _n3)
