Pre Community Bonding

  • Updated subdirectory structure of xapian-letor.
    1. Created subdirectories api/, ranker/, include/xapian-letor/, and move appropriate files to them.
    2. Created xapian-letor.h in include/
  • Refactoring xapian-letor
    1. PIMPL refactoring of FeatureVector class.
    2. Moved include/xapian-letor/letor_internal.h to api/. Since this header had private implementation details, include wasn't the right place for it.
    3. Removed evalmetric module since it was non-functional.
    4. PIMPL refactoring of FeatureManager class (Created featuremanager_internal.h and in api/ which hides away the private implementation details).
    5. Updated/added documentation comments in public API headers.
