Description
Base class for imperative SDN configuration using JavaConfig.
Base class for reactive SDN configuration using JavaConfig.
A callback that can be used to modify an instance of a
Neo4jPersistentEntity after it has been converted:
That is, when a Neo4j record has been fully processed and the entity and all its associations have been processed.Warning Internal API, might change without further notice, even in patch releases.
EntityCallback to populate auditing related fields on an entity about to be bound to a record.Entity callback triggered before an Entity is bound to a record (represented by a
java.util.Map<String, Object>).This is a utility class that computes the bounding box of a polygon as a rectangle defined by the lower left and
upper right point.
An internally used CDI
Qualifier to mark all beans produced by our
configuration support as built in.This annotation indicates a
persistent property
that is composed of multiple properties on a node or relationship.The default implementation, passing map properties through as they are on the way to the graph and possibly
applying a post processor on the way out of the graph.
The default operation for transforming the keys.
Phase of the mapping currently taking place.
A pool of constants used in our Cypher generation.
This annotation can be used to define either custom conversions for single attributes by specifying a custom
Neo4jPersistentPropertyConverter and if needed, a custom factory to create that converter or the annotation
can be used to build custom meta-annotated annotations like @org.springframework.data.neo4j.core.support.DateLong.Indicates an unset converter.

properties that describe the relationship in case of more than a simple relationship.Bridging between Spring Data domain Objects and Cypher constructs.

conditions of the
Cypher-DSL.An interface that can be added to any imperative repository so that the repository exposes several methods taking in
a

way in contrast to provide custom queries declaratively via @Query
annotations.A generator based on the schema defined by node and relationship descriptions.

work.
