- // module_comparer.h: ModuleComparer reads a string format of symbol file, and
- // loads the symbol into both BasicSourceLineResolver::Module and
- // FastSourceLineResolve::Module. It then traverses both Modules and compare
- // the content of data to verify the correctness of new fast module.
- // ModuleCompare class is a tool to verify correctness of a loaded
- // FastSourceLineResolver::Module instance, i.e., in-memory representation of
- // parsed symbol. ModuleComparer class should be used for testing purpose only,
- // e.g., in fast_source_line_resolver_unittest.
