Creating Polite Long-Running Methods

The final step in providing a clean shutdown is to make any long-running methods behave politely. Methods that might run for a long time should check the value of the field that notifies them of shutdowns and should interrupt their work, if necessary.

public void doPost(...) {
   ...
   for(i = 0; ((i < lotsOfStuffToDo) && 
      !isShuttingDown()); i++) {
      try {
         partOfLongRunningOperation(i);
      } catch (InterruptedException e) {
         ...
      }
   }
}
