Class JobParametersBuilder

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

public class JobParametersBuilder
extends Object

Helper class for creating JobParameters. Useful because all JobParameter objects are immutable, and must be instantiated separately to ensure typesafety. Once created, it can be used in the same was a java.lang.StringBuilder (except, order is irrelevant), by adding various parameter types and creating a valid JobParameters once finished.
