is CloudClient supports concurrency? [message #1725589]

Hi all,

In my project I have several Runnable class. In specific periods, this runnable objects publish some data to mqtt server. My questions;

1) What if 2 or more tasks try to use cloudClient what will be happened? (Does two messages will send or something else?)

2) As I said, I have several runnables. In Kura examples, runnables are in the Main class so this runnables use cloudClient and other services. I want to create Classes that implements Runnable interfaces. As you know, I intent to use cloudClient in my runnables. What is the proper way to carry my services to this runnable class? Should I define getter in Main class, or pass cloudClient as an argument to runnable class constructor or something else?

Thanks in advance,
Regards,
Said.

Hi Said,
regarding point 1 I think that the different runnable in your bundle will share the same cloudClient handle. The publish method is composed by synchronized methods, so it should be no problem.
Regarding point 2, yes, you could pass the cloudClient as an argument of the class constructor.

Best regards,
Matteo

Hi Matteo,

I noticed that I will also need other services from the Main class and properties (comes from web ui). So I decided to pass

this

as an argument. So In my runnable classes, I have Main Class object and I can get whatever I need (services, properties etc.). I think this way is a little bit better.

Thank you for your answer,
Regards,
Said.
