类 JobParameters

  • 所有已实现的接口:
    java.io.Serializable
    public class JobParameters
extends java.lang.Object
implements java.io.Serializable
    Value object representing runtime parameters to a batch job. Because the parameters have no individual meaning outside of the JobParameters they are contained within, it is a value object rather than an entity. It is also extremely important that a parameters object can be reliably compared to another for equality, in order to determine if one JobParameters object equals another. Furthermore, because these parameters will need to be persisted, it is vital that the types added are restricted. This class is immutable and therefore thread-safe.
