Class TaskExecutorStatus

java.lang.Object
  org.schmant.run.TaskExecutorStatus

public class TaskExecutorStatus
extends Object

This object represents the current status of a TaskExecutor. It keeps track of the current number of waiting tasks and the current number of running tasks in the executor. It also keeps track of all failed tasks.

Each time a task reports that it is is done via setDone() (which it does even if it fails), this class calls Object.notifyAll() to wake up all threads waiting for the object's monitor. This is used by TaskExecutor.waitFor().

The methods of this class are protected by the intrinsic lock (synchronized).

Scripts don't have to care about this.
