@NonNullApi package org.springframework.data.neo4j.core.mapping
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.

ClassDescriptionWarning Internal API, might change without further notice, even in patch releases.A pool of constants used in our Cypher generation.The
CreateRelationshipStatementHolderholds the Cypher Statement to create a relationship as well as the optional properties that describe the relationship in case of more than a simple relationship.A generator based on the schema defined by node and relationship descriptions.
Converterto instantiate DTOs from fully equipped domain objects.
Converterto instantiate entity objects from DTOsUsed to keep the raw result around in case of a DTO based projection so that missing properties can be filled later on.Provides minimal information how to map class attributes to the properties of a node or a relationship.Description how to generate Ids for entities.This class is not part of any public API and will be changed without further notice as needed.Class that defines a tuple of relationship with properties and the connected target entity.A wrapper or marker for a Neo4j
MapValuethat needs to be unwrapped when used for properties.This orchestrates the built-in store conversions and any additional Spring converters.A builder for creating custom instances of a
PersistentEntityinterface with additional methods for metadata related to Neo4j.A
PersistentPropertyinterface with additional methods for metadata related to Neo4j.Working on nested relationships happens in a certain algorithmic context.This stores all processed nested relations and objects during save of objects so that the recursive descent can be stopped accordingly.Valid processing states.Describes how a class is mapped to a node inside the database.A
NoRootNodeMappingExceptionis thrown when the entity converter cannot find a node or map like structure that can be mapped.The characteristics of a
Neo4jPersistentPropertycan diverge from what is by default derived from the annotated classes.Something that makes sense of propertyPaths by having an understanding of projection classes.Wrapper class for property paths and information if they point to an entity.A very loose coupling between a dot path and its (possible) owning type.Warning Internal API, might change without further notice, even in patch releases.A strategy for traversing all properties (including association) once, without going in circles with cyclic mappings.Description of a relationship.Contains the descriptions of all nodes, their properties and relationships known to SDN.Thrown when required information about a class or primary label is requested from the
Schemaand that information is not available.
