IdDescription	Description how to generate Ids for entities.
MappingSupport
Neo4jMappingContext	An implementation of both a Schema as well as a Neo4j version of Spring Data's MappingContext.

NestedRelationshipProcessingStateMachine.ProcessState	Valid processing states.

Exception Summary

Exception	Description
NoRootNodeMappingException	A NoRootNodeMappingException is thrown when the entity converter cannot find a node or map like structure that can be mapped.

Package org.springframework.data.neo4j.core.mapping Description

The main mapping framework. This package orchestrates the reading and writing of entities and all tasks related to it. The only public API of this package is the subpackage callback, containing the event support. The core package itself has to be considered an internal api and we don't give any guarantees of API stability.
