Warning: among API changes in this release, Application::Start and |
285 |
Application::Stop now interprets the time argument as a relative |
|
286 |
instead of absolute simulation time, to align with how Simulator::Schedule |
|
287 |
behaves. Any code that calls these APIs in the middle of the simulation |
|
288 |
will need to be adapted. |
|
289 |
||
290 |
The API of Simulator::StopAt (time) has also changed. Now it is |
|
291 |
called Simulator::Stop (time), and takes a relative time, instead of |
|
292 |
absolute. |
