Eclipse RCP:检查作业是否完成 [英] Eclipse RCP: check if a job has finished

问题描述

我想检查

I want to check if a Job has finished. Currently I do this:

 if ( traceJob.getState() != Job.WAITING && traceJob.getState() != Job.RUNNING){

但是我认为应该有一个更好的检查方法.任何人都有什么好主意吗?

But I think there should be a better way to check. Anyone has any good idea ?

推荐答案

您可以使用 Job.addJobChangeListener 将侦听器添加到Job.作业完成后，将调用侦听器的 done 方法.有一个 JobChangeAdapter 类，该类具有所有 IJobChangeListener 方法的默认实现，因此您无需实现所有这些方法.

You can use Job.addJobChangeListener to add a listener to a Job. The done method of the listener is called when the job finishes. There is a JobChangeAdapter class with default implementations of all the IJobChangeListener methods so that you don't need to implement all of them.

您可以使用 Job.getJobManager().join(家庭，进度监视器)等待作业完成.这要求您的Job覆盖 belongsTo 方法，以测试Job属于哪个家族.还有 Job.join()等待特定的作业完成.

You can use Job.getJobManager().join(family, progress monitor) to wait for a Job to finish. This requires your Job to override the belongsTo method to test which family the Job belongs to. There is also Job.join() to wait for a specific job to finish.
