Question

I am looking for something similar as Queue type in Python in Groovy language.

In python Queues let to exchange information between threads and take care about all locking problems/challenges. So one thread can simply add a task to queue

while True:
    if self.task_ready():
        task = self.get_task()
        self.queue.put(task) 
        print 'Task %s added to queue' % (task.name)

and worker threads can:

while True:
    self.queue.get()  # this is read blocking action
    self.proces_task(task)

is there a way to do it in such easy way in Groovy?

Answer 1

You could use a Queue.

Java has LinkedBlockingQueue in its java.util.concurrent package which you can just use from Groovy. There’s an article over here on JavaLobby that discusses these structures (obviously from a Java perspective, but you can use the all from Groovy)
