Package org.springframework.data.neo4j.core

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

This package contains the core infrastructure for creating an imperative or reactive client that can execute queries. Packages marked as `@API(status = API.Status.STABLE)` are safe to be used. The core package provides access to both the imperative and reactive variants of the client and the template.
