<<extension>> Configures the thread in a DomainParticipant that handles timed events.
In a dds::domain::DomainParticipant, a thread is dedicated to handle all timed events, including checking for timeouts and deadlines and executing internal and user-defined timeout or exception handling routines/callbacks.
This QoS policy allows you to configure thread properties such as priority level and stack size. You can also configure the maximum number of events that can be posted to the event thread. By default, a dds::domain::DomainParticipant will dynamically allocate memory as needed for events posted to the event thread. However, by setting a maximum value or setting the initial and maximum value to be the same, you can either bound the amount of memory allocated for the event thread or prevent a dds::domain::DomainParticipant from dynamically allocating memory for the event thread after initialization.
This QoS policy is an extension to the DDS standard.

Event& rti::core::policy::Event::thread | ( | const rti::core::ThreadSettings & | the_thread | ) |
Event thread QoS.
There is only one event thread.
