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

@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.
