OMNeT++ Discrete Event Simulator
Role in this project:
Back-end Developer
Back-end DeveloperContributions:11 releases, 17932 commits, 7 PRs in 24 years
Contributions summary:András's contributions involved porting the `cXMLElement` class to utilize `opp_pooledstring` and `std::vector` for memory optimization. They refactored the `pooledstring.h/cc` files, splitting the stringpool implementation and fixing the assignment operator for `opp_pooledstring` to prevent memory leaks. Additionally, the user implemented or refined a number of methods related to processing config properties, including adding value origin metadata and support for expressions.
