That is, the object is reset and available to generate another signature with the same private key, if desired, via new calls to update and sign.Alternatively, a new call can be made to initSign specifying a different private key, or to initVerify (to initialize the Signature object to ...
ArrayBlockingQueue:由数组组成的有界阻塞队列,FIFO DelayQueue:一个延时无界阻塞队列,内部包含了PriorityQueue(一个由优先级堆构成的无界队列) DelayedWorkQueue:这个属于ThreadPoolExecutor的内部类,专门来储存RunnableScheduledFuture任务的,也是一个基于堆的延时队列 ...
