Examples of org.apache.lucene.store.IndexOutput.writeVInt()

org.apache.lucene.store.IndexOutput.writeVInt()
Writes an int in a variable-length format. Writes between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported. @see IndexInput#readVInt()

            // Write the Version info - must be a VInt because CFR reads a VInt
            // in older versions!
            os.writeVInt(FORMAT_CURRENT);
            
            // Write the number of entries
            os.writeVInt(entries.size());


            // Write the directory with all offsets at 0.
            // Remember the positions of directory entries so that we can
            // adjust the offsets later
            long totalSize = 0;
