Class Neo4jPersistentEntity<T>

java.lang.Object

org.springframework.data.mapping.model.BasicPersistentEntity<T,Neo4jPersistentProperty>

org.springframework.data.neo4j.mapping.Neo4jPersistentEntity<T>

All Implemented Interfaces:

Iterable<Neo4jPersistentProperty>, MutablePersistentEntity<T,Neo4jPersistentProperty>, PersistentEntity<T,Neo4jPersistentProperty>

public class Neo4jPersistentEntity<T>
extends BasicPersistentEntity<T,Neo4jPersistentProperty>

This class implements Spring Data's PersistentEntity interface, scavenging the required data from the OGM's mapping classes in order to for SDN to play nicely with Spring Data REST. The main thing to note is that this class is effectively a shim for ClassInfo. We don't reload all the mapping information again.

These attributes do not appear to be used/needed for SDN 4 to inter-operate correctly with SD-REST:

• typeAlias
• typeInformation
• preferredConstructor (we always use the default constructor)
• versionProperty

Consequently their associated getter methods always return default values of null or [true|false] However, because these method calls are not expected, we also log a warning message if they get invoked

Since:

4.0.0
