Package org.springframework.batch.core

@NonNullApi package org.springframework.batch.core

Core domain context for Spring Batch covering jobs, steps, configuration and execution abstractions. Most classes here are interfaces with implementations saved for specific applications. This is the public API of Spring Batch. There is a reference implementation of the core interfaces in the execution module.
