Examples of org.eclipse.jgit.storage.file.PackIndex

org.eclipse.jgit.storage.file.PackIndex
Access path to locate objects by {@link ObjectId} in a {@link PackFile}.
Indexes are strictly redundant information in that we can rebuild all of the data held in the index file from the on disk representation of the pack file itself, but it is faster to access for random requests because data is stored by ObjectId.

        PackReverseIndex revidx = revref.get();
        if (revidx != null)
          return revidx;
      }


      PackIndex idx = idx(ctx);
      PackReverseIndex revidx = new PackReverseIndex(idx);
      int sz = (int) Math.min(
          idx.getObjectCount() * 8, Integer.MAX_VALUE);
      reverseIndex = cache.put(key, POS_REVERSE_INDEX, sz, revidx);
      return revidx;
    }
  }
