Class JobParametersBuilder

java.lang.Object
  org.springframework.batch.core.JobParametersBuilder

public class JobParametersBuilder
extends Object

Helper class for creating JobParameters. Useful because of all JobParameters are immutable, and require 3 separate maps of the three supported types to ensure typesafety. Once created, it can be used in the same was a java.lang.StringBuilder (except, order is irrelevant), by adding various parameters types and creating a valid JobRuntimeParametres once finished.
