SObjectizer Tales - 27. Design ideas
An additional rationale for structuring cooperations in hierarchies is to facilitate the sharing and propagation of dispatchers. A recent update of SObjectizer includes new functionalities that allow access to both agent and cooperation dispatchers. This enhancement was prompted by feedback provided by a user and myself.

SObjectizer Tales - 26. Dispatcher selection
If a stop signal arrives, it will be enqueued at the end as a demand for image_producer_callback. This means, it will be processed after the other 6 demands currently in the queue. Maybe this is not an issue but in some cases it might be. At this point, another feature of SObjectizer is to consider: agent priorities. Essentially, this feature allows for the demands to be handled in different orders based on the priorities of agents. In this context, if we assign image_producer_callback a higher priority than others, the “stop signal” would be processed before the rest of the requests.

SObjectizer Tales - 23. Mutable messages
The real solution consists in using another slick feature of SObjectizer: mutable messages.

SObjectizer Tales - 8. Representing errors
However, this kind of filtering is inefficient and might result in a significant run-time cost. Indeed, every empty cv::Mat follows all the message handling workflow, only to be thrown out. Although we expect that empty images will be sporadic, a more idiomatic approach exists: delivery filters.

SObjectizer Tales – 6. Is the stream still in progress?
SObjectizer’s agent states are quite sophisticated and provide some utilities that might be useful for developing a working solution. First of all, image_viewer can be modeled as a two-state agent:

An alternative way is using SObjectizer’s timers.

What are some candidate libraries for inter-thread communication like message boxes or event systems?
In sobjectizer the ownership is held by "environment" , while in rotor each thread must held appropriate context, when actor environment is running.
