Examples of JsrFlow

org.springframework.batch.core.jsr.job.flow.support.JsrFlow
Implements JSR-352 specific logic around the execution of a flow. Specifically, this {@link Flow} implementation will attempt to find the next state based on the providedexit status. If none is found (the exit status isn't mapped), it will attempt to resolve the next state basing it on the last step's batch status. Only if both attempts fail, the flow will fail due to the inability to find the next state. @author Michael Minella @since 3.0
