Re: [Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Hi all,

Is it possible to detect the "Pause" operation of the Jason & Cartago
container, because I would like to stop my extra thread-controlled timer
when the container is paused? Is there any operation for this?


Thank you for your help.

Best regards.
