See: Description

Interface Summary

Interface	Description
GraphPropertyDescription	Provides minimal information how to map class attributes to the properties of a node or a relationship.
Neo4jEntityConverter	This orchestrates the built-in store conversions and any additional Spring converters.
Neo4jPersistentEntity<T>	A PersistentEntity interface with additional methods for metadata related to Neo4j.
Neo4jPersistentProperty	A PersistentProperty interface with additional methods for metadata related to Neo4j.
NodeDescription<T>	Describes how a class is mapped to a node inside the database.
RelationshipDescription	Description of a relationship.
Schema	Contains the descriptions of all nodes, their properties and relationships known to SDN.

Class Summary

Class	Description
Constants	A pool of constants used in our Cypher generation.
CreateRelationshipStatementHolder	The CreateRelationshipStatementHolder holds 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.
DtoInstantiatingConverter	Converter to instantiate DTOs from fully equipped domain objects.
EntityFromDtoInstantiatingConverter<T>	Converter to instantiate entity objects from DTOs
EntityInstanceWithSource	Used to keep the raw result around in case of a DTO based projection so that missing properties can be filled later on.
IdDescription	Description how to generate Ids for entities.
MappingSupport
MappingSupport.RelationshipPropertiesWithEntityHolder	Class that defines a tuple of relationship with properties and the connected target entity.
Neo4jMappingContext	An implementation of both a Schema as well as a Neo4j version of Spring Data's MappingContext.
NestedRelationshipContext	Working on nested relationships happens in a certain algorithmic context.
NestedRelationshipProcessingStateMachine	This stores all processed nested relations and objects during save of objects so that the recursive descent can be stopped accordingly.
PropertyFilter	Something that makes sense of propertyPaths by having an understanding of projection classes.
PropertyFilter.RelaxedPropertyPath	A very loose coupling between a dot path and its (possible) owning type.

Enum Summary

Enum	Description
CypherGenerator	A generator based on the schema defined by node and relationship descriptions.
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.
UnknownEntityException	Thrown when required information about a class or primary label is requested from the Schema and that information is not available.

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.
