Hi,
I am new to the Eclipse Job API and have a few basic questions.
1. Can I think of org.eclipse.core.runtime.jobs.Job as Java Runnable?
2. If I have:
MyJob1 a = new MyJob1();
MyJob2 b = new MyJob2();
MyJob3 c = new MyJob3();
a.schedule();
b.schedule();
c.schedule();
Will a, b, and c be running in the same worker thread sequentially? Or
will they be running in 3 threads in parallel? If the former is true, what
is the general mechanism to run different jobs in different threads
parallelly? Can you please give an example?
Thanks in advance!
Sunny

Jobs are similar to Runnable but are connected to a scheduling system
that allocates them to threads automatically. In your

They may run either sequentially or concurrently, since you haven't
expressed any dependency between these three jobs. For a more detailed
answer see the documentation:
