workmanager

任务调度管理类

version beta 0.1

1. 一般的线性方式

A => B => C WorkManager.getInstance().beginWith(A).then(B).then(c).enqueue();

2. 带分支的调用

   || => B => D => || A => || || =>F || => C => E => ||

WorkChain wc1 = new WorkChain();
wc1.addWork(B).addWork(D);
WorkChain wc2 = new WorkChain();
wc2.addWork(B).addWork(D);
WorkManager.getInstance().beginWith(A).then(wc1, wc2).then(F).enqueue();

3. 更复杂的分支


     || => B  => ||
     ||          || => E => ||
A => || => C  => ||         ||
     ||                     || => G
     || => D  =======> F => ||

WorkChain wc1 = new WorkChain();
wc1.addWork(D).addWork(F);
WorkChain wc2 = new WorkChain();
wc2.addWork(B, C).addWork(E);

WOrkManager.getInstance().beginWith(A).then(wc1, wc2).then(G).enqueue();


4. 暂停或者退出Activity时，停止执行任务链

WorkManager wm = WorkManager.getInstance();
wm.addWork(A, B).then(D).then(E).enqueue();

onDestroy or somewhere:
wm.clear();
