Description

Abstract

This PR reduces the build time of openscenario_interpreter by suppressing heavy template instantiation.

Background

openscenario_interpreter heavily relies on templated components. These components are typically instantiated and optimized per translation unit, which can lead to longer build times.

Details

Added several explicit instantiations to readAttribute and moved the substitute() function used internally to the cpp file. No changes were made to the algorithm itself.

Added several explicit instantiations to readElement. Additionally, the choice() function was made non-template and its implementation was moved to the cpp file. No changes were made to the algorithm itself. Due to this change, the arguments of the choice() function have changed from "variadic arguments of std::pair" to "std::unordered_map," resulting in a slight modification in how the arguments are described in the places where choice() is called. Most of the changes in the diffs are due to this modification.

Removed the template specialization declarations in DistanceCondition / RelativeDistanceCondition. There are no impacts on other classes due to this change. With the removal of the declarations, the implementation of the distance() function has been moved after the specialization.
