Examples of org.apache.lucene.store.IndexInput.readVInt()

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

      FieldInfo infos[] = new FieldInfo[size];


      for (int i = 0; i < size; i++) {
        String name = input.readString();
        final int fieldNumber = input.readVInt();
        byte bits = input.readByte();
        boolean isIndexed = (bits & Lucene46FieldInfosFormat.IS_INDEXED) != 0;
        boolean storeTermVector = (bits & Lucene46FieldInfosFormat.STORE_TERMVECTOR) != 0;
        boolean omitNorms = (bits & Lucene46FieldInfosFormat.OMIT_NORMS) != 0;
