C++ provides a rich and handy library called Standard Template Library that is based on the generic programming paradigm. STL includes many useful containers like vector, linked lists, etc. The selection of the utilized container may have a significant impact on the developed applications’ performance regarding runtime, memory consumption and management, etc. Unfortunately, the architecture of the library does not support altering this selection in a straighforward way. Evaluation of the selection can be quite difficult. Different containers may have methods with the same name, but they can differ in the provided methods and iterator capabilities. In this paper, we present a static analyzer tool that aims at the manipulation of a container type by changing it in existing code bases. The proposed tool is based on the Clang compiler infrastructure. For making the transformation seemless, we provide some class templates to hide the differences of methods.
